TJOFLAT, Circuit Judge:

I. STATEMENT OF THE CASE

A. *Factual Background*

On October 20, 2000, Jermaine Williams and Lowen Espinueva attempted to rob an armored car in Coral Springs, Florida. As the armored car’s drivers (Frank Granja and Eshaman Ruiz) were restocking an ATM with cash, Williams and Espinueva drove up and started shooting at them. Espinueva used a 12-gauge shotgun, while Williams was firing a 9-millimeter pistol; *1233both guards were seriously wounded. When the guards returned fire, Williams and Espinueva fled without stealing any money.

Williams and Espinueva were later arrested and indicted on three counts: conspiring to obstruct interstate commerce through robbery (Count I),1 attempting to obstruct interstate commerce through robbery (Count II),2 and discharging a firearm in connection with a crime of violence (Count III).3 Williams pled guilty to all three counts and was sentenced to 200 months in prison by the United States District Court for the Southern District of Florida.4 This includes 80 months for Counts I and II, and a mandatory consecutive 120-month sentence for Count III.5 This appeal concerns Williams’s prison sentence for Counts I and II.

B. *Williams’s Sentence*

Under the sentencing guidelines, the various charges of which a defendant is convicted are sorted into different “groups” based on the rules set forth in United States Sentencing Commission, *Guidelines Manual,*§ 3D (Nov.2002). In general, related charges are supposed to be grouped together, while charges arising from separate incidents are supposed to be grouped apart from each other. “In essence, counts that are grouped together are treated as constituting a single offense for purposes of the guidelines.” *Id.,*ch. 3, pt. D, introductory cmt. (2002). Each group is assigned a numerical “offense level,” which is determined by the most serious offense in that group. *See id.*§ 3D1.3(a). Based on the number of groups the defendant has, as well as each group’s offense level, the defendant is assigned a “combined offense level,” which is used to determine his sentence. *See id.*§ 3D1.4. As a result of this system, a defendant will receive a much higher sentence if two crimes are grouped separately than if they are grouped together.6 Sec*1234tion 3D1.2 of the Sentencing Guidelines states that multiple offenses may be grouped together only “[w]hen counts involve the same victim and the same act or transaction,” U.S.S.G. § 3D1.2(a), or “[w]hen counts involve the same victim and two or more acts or transactions connected by a common criminal objective or constituting part of a common scheme or plan,” *id.*§ 3D1.2(b).7

The Pre-Sentence Investigation Report (“PSI”) completed by Williams’s probation officer recommended that Counts I and II be assessed separately under the guidelines rather than grouped together. The report claimed, “Counts One and Two represent separate harms and are specifically excluded from grouping rules in § 3D1.2.... Group One will represent the harm caused to Frank Granja and Group Two will represent the harm caused to Eshaman Ruiz.” Williams filed an objection to the report, stating “Counts One and Two of the indictment, which charge a conspiracy to commit a robbery and an attempt to commit a robbery, are part of a single criminal episode and should be grouped together, pursuant to § 3D1.2(b).” The probation officer again declined to group Counts I and II together, emphasizing that “[t]he counts cannot be grouped under either § 3D1.2(a) or (b) since neither count involved the same ‘victim.’”

Williams then filed an objection to the amended report with the district court, arguing yet again that Counts I and II (conspiracy to commit robbery and the attempted robbery) should have been grouped together. The district court, without explanation, overruled Williams’s objection and adopted the recommendation of the PSI, putting each charge in a separate group in calculating Williams’s sentence. Because Counts I and II were grouped separately, Williams’s sentencing range for these counts was 78-97 months; the judge sentenced him to 80 months (plus a mandatory consecutive 120-month sentence for Count III). Had Counts I and II been grouped together, Williams would be eligible for a sentence of between 63-78 months, in addition to his mandatory sentence for Count III.

II. STANDARD OF REVIEW

Before turning to the substance of Williams’s claims, it is first necessary to determine the appropriate standard of review. Federal law states, “The court of appeals ... shall accept the findings of fact of the district court unless they are clearly erroneous and, ... shall give due deference to the district court’s application of the guidelines to the facts.” 18 U.S.C. § 3742(e). Our precedent clearly follows the first part of this statute, requiring us to review district courts’ factual findings under a “clear error” (or “clearly erroneous”) standard.8*See United States v. Maung,*267 F.3d 1113, 1118 (11th Cir.2001) (“When a defendant challenges the *1235district court’s application of the sentencing guidelines, we review the district court’s underlying findings of fact for clear error.... ”). For example, “[a] district judge’s attribution of drugs to a particular defendant under the Sentencing Guidelines is subject to clearly erroneous review.” *United States v. Alred,*144 F.3d 1405,1416 (11th Cir.1998). Similarly, “[possession of a firearm for sentencing purposes is a factual finding ... reviewed under a clearly erroneous standard.” *United States v. Geffrard,*87 F.3d 448, 452 (11th Cir.1996). The proper standard of review for a district court’s application of the sentencing guidelines to the facts of a particular case, also referred to as “mixed questions of fact and law” involving the guidelines, is much less settled. Section 3742’s “due deference” language has proven to be a source of great ambiguity within this circuit, and our caselaw is, to say the least, muddled. Subpart A begins by explaining the various approaches this circuit has taken in considering this matter. Subpart B goes on to explain how “due deference” should not be interpreted as establishing a fixed quantum of review, but instead requires varying degrees of deference to the lower courts based on the precise nature of the guideline provision at issue. Subpart C applies these principles to determine the appropriate standard of review in the instant case.

A. *Prior Interpretations of § 3742(e)’s “Due*Deference” *Language*

18 U.S.C. § 3742(e) requires the court of appeals to accord “due deference” to a district court’s ruling on how the sentencing guidelines should be applied to the facts before it. Our precedents have not implemented this provision in a wholly consistent manner. This subpart attempts to explain our circuit’s various interpretations of the proper standard of review for guidelines cases.

1. *Ignoring 18 U.S.C. § 374.2(e)*— We have characterized “question[s] about whether a particular guideline applies to a given set of facts” both as questions of law, *see United States v. Shriver,*967 F.2d 572, 574 (11th Cir.1992), and (more appropriately) as mixed questions of fact and law, *see United States v. Scroggins,*880 F.2d 1204, 1206 n. 5 (11th Cir.1989). In general, *de novo*review is appropriate for both types of issues. *See, e.g., Parker v. Sec’y for the Dep’t of Corrs.,*331 F.3d 764, 765 (11th Cir.2003) (“We review the district court’s findings of fact for clear error and its legal conclusions and mixed questions of law and fact de novo.”).

It is possible that prior panels simply applied these general principles and, as a result, overlooked § 3742(e) and its “due deference” standard. Consequently, many of our eases simply state, “This court reviews the district court’s sentencing hearing findings of fact for clear error and its application of the sentencing guidelines to those facts *de novo.” United States v. Renick,*273 F.3d 1009, 1021 (11th Cir.2001); *accord United States v. De La Mata,*266 F.3d 1275, 1302 (11th Cir.2001); *Maung,*267 F.3d at 1118; *United States v. Jamieson,*202 F.3d 1293, 1295 (11th Cir. 2000); *United States v. Gallo,*195 F.3d 1278, 1280 (11th Cir.1999); *United States v. Herrera,*931 F.2d 761, 762 (11th Cir. 1991). Even if, in these cases, § 3742’s due deference standard was interpreted to mean *de novo*review, it is both confusing and improper for a court of appeals, or the parties appearing before it, to fail to cite this statute (or a case interpreting this statute) in a sentencing guidelines appeal.

By its very terms, § 3742 clearly applies to sentencing guidelines cases. Moreover, we reject the notion that Congress intended § 3742’s due deference standard to leave undisturbed our general *de novo*standard for reviewing issues concerning *1236the application of the law to particular sets of facts. This “due deference” language was undoubtedly intended to require, at least in some cases, greater respect for district court holdings than is traditionally accorded under *de novo*review. *See United States v. Malone,*78 F.3d 518, 520-21 n. 2 (11th Cir.1996) (“The ‘due deference’ standard in 18 U.S.C. § 3742 ‘serves as an additional caution against overly intense judicial review.’ ” (quoting *United States v. Mejia-Orosco,*868 F.2d 807, 808 (5th Cir.1989))).

2. *“Due deference” always means de novo review*— Many of our cases, despite quoting the due deference standard from § 3742(e), nevertheless proclaim in sweeping terms that “we review the district court’s application of the Sentencing Guidelines *de novo.” United States v. Ortiz,*318 F.3d 1030, 1036 (11th Cir.2003) (internal citation omitted); *see also United States v. Hall,*312 F.3d 1250, 1260 n. 12 (11th Cir.2002); *United States v. Singh,*291 F.3d 756, 763 (11th Cir.2002); *United States v. Smith,*231 F.3d 800, 806-07 (11th Cir.2000). As noted above, we refuse to interpret the phrase “due deference” as used in § 3742 as establishing a blanket *de novo*standard. While, for reasons explained later in this opinion, due deference may have required some panels to apply *de novo*review in certain cases (given their facts and the particular guidelines at issue), those cases should not be read as establishing a general proposition that due deference always means *de novo.*

3. *Due deference always means clear error review*— At least one of our cases has also strayed to the other extreme, holding “[W]e review for clear error the district judge’s application of the guidelines to the facts of the case.” *Calderon,*127 F.3d at 1339. We also arguably equated the due deference and clear error standards in *United States v. De Varon,*175 F.3d 930 (11th Cir.1999) (en banc), where we held, “[A] district court’s determination of a defendant’s role in the offense is a finding of fact to be reviewed only for clear error. ... [It is] a fundamentally factual determination entitled to due deference and not a legal conclusion subject to *de novo*review.” *Id.*at 937-38. These quotes might suggest that the clear error and due deference standards were interchangeable for reviewing a district court’s findings of fact.

It is clearly inconsistent with the overwhelming weight of the precedents discussed above to conclude that due deference always means clear error, or that clear error is always the appropriate standard for reviewing a district court’s application of the guidelines to a particular case. Moreover, such conclusions are contrary to the clear text of § 3742, which states that although a district court’s factual determinations should be reviewed under a “clear error” standard, its application of the law should be given only “due deference.” This deliberate variation in terminology within the same sentence of a statute suggests that Congress did not interpret the two terms as being equivalent. *See United States v. Bean,*537 U.S. 71, 123 S.Ct. 584, 587 n. 4, 154 L.Ed.2d 483, 489 n. 4 (2002) (“The use of different words within related statutes generally implies that different meanings were intended.” (quoting 2A N. Singer, *Sutherland on Statutes and Statutory Construction*§ 46.06, at 194 (6th ed.2000))). While clear error review may have been warranted for the guideline at issue in *Calderon,*our precedents should not be read as establishing a uniform rule of always equating the due deference standard with clear error review.

*4.Due deference is either a fixed standard of review independent of the de novo and clear error standards, or a type of de novo review*— Many of our cases set forth *1237our general *de novo*standard for reviewing mixed questions of fact and law, then cite § 3742’s “due deference” standard for mixed questions involving application of the sentencing guidelines. For example, *United States v. Yount*states, “[W]e give due deference to the district court’s application of the guidelines to the facts.... The district court’s application of law to the facts is reviewed *de novo.”*960 F.2d 955, 956 (11th Cir.1992); *accord United States v. Geffrard,*87 F.3d 448, 452 (11th Cir.1996) (“[T]he application of the law to the facts found is reviewed *de novo.*The application of the guidelines to the facts, however, is entitled to ‘due deference.’” (citation omitted)); *Singh,*291 F.3d at 763.9

These passages are misleading on several grounds. First, in distinguishing between application of “the guidelines” and application of “the law,” they obscure the fact that the guidelines are the law. Second, the passages can be interpreted in two different ways, both of which are erroneous. On the one hand, one might interpret this passage to mean that we review *de novo*all mixed questions of fact and law, including questions involving application of the guidelines, but in the course of doing so we somehow accord the district court’s ruling some special degree of deference. This is apparently the approach we took in *United States v. Hall,*where we held, “Although this Court, *as part of its de novo review,*gives due deference to the district court’s application of the guidelines to the facts, this Court is not bound by the district court’s application of the guidelines to the facts and our review remains *de novo.”*312 F.3d 1250, 1262 n. 16 (11th Cir.2002) (emphasis added). This understanding is also conveyed by cases such as *United States v. McIntosh*wherein we held, “We review the district court’s application of the sentencing guidelines *de novo,*giving due deference to the district court’s refusal to group multiple counts under U.S.S.G. § 3D1.2.” 216 F.3d 1251, 1253 (11th Cir.2000).

It is unclear how we can give due deference to a district court’s conclusions when applying *de novo*review, since *de novo*review requires us to look at a question as if we are the first court to consider it. Put simply, it is definitionally impossible to give deference of any sort to a decision being reviewed *de novo.*Moreover, none of these cases explains how a *de novo*review involving “due deference” to the district court would differ from a *de novo*review not involving such deference. Thus, the *Hall/McIntosh*interpretation of the above-quoted passage from *Yount*is both unenlightening and internally contradictory.

The only other possible interpretation is that while *in general*we review mixed questions of fact and law *de novo,*we apply a special, independent “due deference” standard when the mixed question involves application of the sentencing guidelines. This would imply that due deference is a standard of intermediate scrutiny falling somewhere between *de novo*and clearly erroneous. This interpretation is not only a stretch, given the text of those opinions, but is also erroneous. For the reasons discussed in the next subpart, we do not believe that Congress intended the phrase “due deference” to establish a new, independent standard of review.

*1238B. *The Correct Interpretation of § S7I2(e)’s “Due Deference” Language*

This subpart attempts to harmonize our precedents concerning the proper standard of review for a district court’s application of the sentencing guidelines to particular factual scenarios (“mixed questions of fact and law” involving the guidelines). We begin with Supreme Court decisions interpreting § 3742(e) that most of our precedents have overlooked. We then turn to a handful of opinions within this circuit that have interpreted § 3742(e) in accordance with both the statute’s clear language as well as these Supreme Court precedents. Finally, in the absence of a case that can clearly be identified as our panel’s earliest definitive ruling on this subject, we set forth general principles to guide future panels in resolving these complex issues.

1. *Supreme Court precedent*— Two Supreme Court cases shed light on § 3742(e). In *Koon v. United States,*518 U.S. 81, 98, 116 S.Ct. 2035, 2046, 135 L.Ed.2d 392 (1996), the Court held, while interpreting § 3742(e)’s “due deference” requirement,

> [t]he deference that is due depends on the nature of the question presented. The district court may be owed no deference, for instance, when the claim on appeal is that it made some. sort of mathematical error in applying the Guidelines; under these circumstances, the appellate court will be in as good a position to consider the question as the district court was in the first instance.

Five years later, in *Buford v. United States,*532 U.S. 59, 121 S.Ct. 1276, 149 L.Ed.2d 197 (2001), the Court applied Koon’s “sliding scale” understanding of “due deference.” The *Buford*Court considered the degree of deference due a district court’s holding that a defendant’s pri- or convictions had not been “functionally consolidated,” to determine whether a § 4B1 enhancement for repeat offenders was appropriate. *Id.*at 63, 121 S.Ct. at 1279.

The *Buford*Court upheld the Seventh Circuit’s decision to apply a particularly deferential standard of review, akin to “clearly erroneous,” to this type of decision. It stated, “[T]he district court is in a better position than the appellate court to decide whether a particular set of individual circumstances demonstrates ‘functional consolidation’ [of prior sentences, because] ... [a]s a trial judge, a district judge is likely to be more familiar with trial and sentencing practices in general, including consolidation procedures.” *Id.*at 64, 121 S.Ct. at 1280. The Court also emphasized:

> The legal question at issue is a minor, detailed, interstitial question of sentencing law.... That question is not a generally recurring, purely legal matter, such as interpreting a set of legal words, say, those of an individual guideline.... Nor is that question readily resolved by reference to general legal principles and standards alone. Rather, the, question at issue grows out of, and is bounded by, case-specific detailed factual circumstances.

*Id.*at 65, 121 S.Ct. at 1280-81.

These cases lead to several conclusions. *Koon*tells us that “due deference” is not a fixed standard of scrutiny akin to *de novo*or “clear error” review, but instead establishes, a, “sliding scale.” When reviewing decisions involving the application of certain types of guidelines, no deference will be due a district court’s rulings, effectively leading to *de novo*review. With other guidelines, an appellate court should accord the trial court’s decisions a high degree of deference, reviewing those rulings under the substantive equivalent of a “clear error” standard.

*Buford*shows us how to distinguish between guidelines requiring significant def*1239erence and those requiring no deference. The two most important factors are: (1) whether the ruling depends on a wide range of facts that are more readily available to the district court than to the court of appeals, due to the district court’s firsthand experience trying the case, and (2) whether the issue primarily involves a legal interpretation of a guideline (suggesting *de novo*review), or instead involves the application of a clearly-established, well-understood legal standard or principle to a detailed fact pattern (indicating “clear error” review). “Clear error” review is particularly appropriate in the latter type of cases because “the fact-bound nature of the decision limits the value of appellate court precedent.” *Buford,*532 U.S. at 65-66, 121 S.Ct. at 1281. These principles are more fully fleshed out with reference to our own precedents, to which we now turn.

2. *The Sliding Scale Interpretation of § 3712 in the Eleventh Circuity*— Despite the wide range of our circuit’s interpretations of § 3742’s “due deference” language, discussed in the previous subpart, our precedents are not entirely without support for the Supreme Court’s sliding scale approach. *See, e.g., United States v. Taylor,*88 F.3d 938, 942 (11th Cir.1996) (recognizing that the meaning of the term “due deference” depends on the particular guidelines at issue). One of our early guidelines cases, *United States v. Malgoza,*2 F.3d 1107 (11th Cir.1993), best exemplifies this understanding of § 3742. Citing the Fourth Circuit, we held, “To say that we review a finding with due deference means that we give the district court the deference that is due in regard to that finding. The deference due will depend upon whether the determination is primarily factual or legal.” *Id.*at 1109 *(citing United States v. Daughtrey,*874 F.2d 213, 217 (4th Cir.1989)). We explained,

> When the district court’s application of sentencing guidelines to facts involves primarily a legal decision, such as the interpretation of a statutory term, less deference is due to the district court than when the determination is primarily factual.... In contrast, when an application of the guidelines to facts is closer to a pure question of fact, the appellate court will review the application with the deference due under the clearly erroneous standard.

*Id.*at 1109-10 (citations omitted). This holding reflects the principles articulated above. Where a determination turns primarily on the evaluation of facts (such as a witness’s credibility, intonation, and demeanor) that are more accessible to the district court than to the court of appeals, we will defer to the district court’s application of the law to those facts and apply “clear error” review. Similarly, a case involving application of a fairly well-understood legal standard to a complex factual scenario will be considered “primarily factual,” and be reviewed for clear error. Most other cases, in contrast, will be reviewed *de novo.*

a. *Specific types of cases in which de novo review is particularly*appropriate— Unless a case falls into one of the categories specified above, *de novo*review of the district court’s application of the law to the facts of the case is generally appropriate. *But see infra*Part I.B.3. Many (but certainly not all) cases in which we apply *de novo*review involve legal issues for which most or all of the relevant facts are contained in the counts in the indictment for which the defendant has been convicted or pled guilty. For example, in *United States v. Smith,*231 F.3d 800 (11th Cir. 2000), one of the defendants was the county’s deputy registrar of voters. She was convicted of, among other things, fraudulently submitting an absentee ballot on behalf of a voter without that voter’s knowledge or consent. We did not have to go far beyond the allegations contained in the indictment to affirm the district court’s *1240ruling that this offense, under the circumstances, involved an “abuse[ ][of| a position of public or private trust.” *Id.*at 819 (quoting U.S.S.G. § 3B1.3). Consequently, there was no special need to defer to the district court’s assessments, and *de novo*review was appropriate. *Id.*at 806 (“We review the district court’s application of the Sentencing Guidelines *de novo*.... ”). Similarly, in *United States v. Singh,*291 F.3d 756, 762 (11th Cir.2002), we reviewed the district court’s interpretation of U.S.S.G. § 2Fl.l(b)(6), which provides for an offense-level enhancement if part of a fraud is committed outside of the United States. Because it was undoubtedly apparent from the indictment whether part of the fraud for which the defendant was convicted had occurred in a different country, *de novo*review was appropriate. *See Singh,*291 F.3d at 762 *(citing United States v. Bradford,*277 F.3d 1311, 1312 (11th Cir.2002)). Another reason *de novo*review was appropriate in *Singh*was because our opinion focused more on interpreting the guideline’s language than on digging through a complex factual record.

*De novo*review is also warranted in cases where we must determine whether the district court applied the correct sentencing guideline (or subsection of a sentencing guideline) for the defendant’s underlying conduct. *See, e.g., United States v. De La Mata,*266 F.3d 1275, 1302 (11th Cir.2001) (reviewing *de novo*the district court’s decision as to whether the “money laundering” or “fraud” sentencing guideline was more appropriate, given the facts of the case); *Smith,*231 F.3d at 806-07, 818-19 (applying *de novo*review and upholding district court’s decision to apply U.S.S.G. § 2H2.1(a)(2) instead of § 2H2.1(a)(3) because “[t]he offenses for which [defendants] were convicted involved ... the forging of other voters’ names on applications of absentee ballot and affidavits of absentee voter”). Such matters turn primarily on the contents of the indictment-and interpretation of the sentencing guidelines, areas for which we are not especially dependent on district courts.

b. *Specific types of cases in which “clear error” review is particularly appropriate*— A key factor in determining whether “due deference” requires us to review a district court’s application of the guidelines in a particular case is the degree to which its ruling is based upon a variety of “intangible” factors that a district judge is in a better position than we are to assess. With certain types of issues, a variety of considerations may have a significant influence on the judge’s determination, yet cannot be adequately reflected in the cold, barren wasteland of the record. For example, U.S.S.G. § 3C1.1 provides for a two-level enhancement if the defendant engaged in obstruction of justice during the course of the investigation, prosecution, or sentencing of his crime. One way in which a defendant may obstruct justice is by perjuring himself at trial.10*See*U.S.S.G. § 3C1.1, cmt. n. 4(b) (“The following is a non-exhaustive list of examples of the types of conduct to which this adjustment applies: ... committing, suborning, or attempting to suborn perjury.”). An appellate court is not in a position to assess a defendant’s demeanor, apparent sincerity, intonation, expression, gesticulations, and a wide range of other considerations that are pertinent in determining whether he has perjured himself. *See also Owens v. Wainwright,*698 F.2d 1111, 1113 (11th Cir.1983) (“Appellate courts reviewing a cold record give partic*1241ular deference to credibility determinations of a fact-finder who had the opportunity to see live testimony.”); *United States v. De Varon,*175 F.3d 930, 938 (11th Cir. 1999) (en banc) (“Intensely factual inquiries ... are properly consigned to the experienced discretion of the district judge.”); *see also United States v. Abbell,*271 F.3d 1286, 1303 (11th Cir.2001) (“[B]e-cause the demeanor of the pertinent juror is important to juror misconduct determinations, the district court is uniquely situated to make the credibility determinations that must be made in cases like this one: where a juror’s motivations and intentions are at issue”).

Consequently, it is not only appropriate, but necessary, for us to accord special deference to district court rulings under guidelines such as § 3C1.1 when matters such as perjury are at issue (by reviewing the district court’s determinations only for “clear error”). *E.g., Singh,*291 F.3d at 764 (“[W]e cannot say that the district court’s decision to enhance [defendant’s] adjusted offense level pursuant to U.S.S.G. § 3C1.1 was clearly erroneous. Therefore, we affirm the district court on this issue.”). However, because § 3C1.1 encompasses a wide range of conduct which can obstruct justice, we need not examine all § 3C1.1 enhancements with special deference. For example, in *United States v. Taylor,*we reviewed *de novo*a court’s two-level enhancement for obstruction of justice under § 3C1.1 for a defendant who had “repeatedly refused to provide the government with handwriting exemplars, and when he finally did, h[ad] attempted to disguise his writing.” 88 F.3d at 941-42. Unlike the perjury at issue in *Singh,*there was no need for a particularized assessment of the credibility or demeanor of the defendant in *Taylor.*The pertinent conduct (failing to provide the handwriting exemplars) could clearly be set forth in detailed, non-eonclusory findings by the district court, which were accorded great deference. Consequently, we were in a much better position to review *de novo*the district court’s application of the obstruction of justice guideline to those facts than in a typical perjury case. *Id.*at 942. Thus, even with regard to application of a particular guideline, the degree of deference “due” a district court can vary dramatically based on the allegations at issue.

Because of the importance of determining a defendant’s apparent sincerity through firsthand observation, we have also accorded special deference to district court rulings concerning offense-level reductions under § 3E1.1 for a defendant’s acceptance of responsibility, reviewing them under a “clear error” standard as well. *See, e.g., United States v. Brenson,*104 F.3d 1267, 1288 (11th Cir.1997) (“We review the district court’s decision as to acceptance of responsibility only for clear error.”); *United States v. Pritchett,*908 F.2d 816, 824 (11th Cir.1990) (“The district court is in a unique position to evaluate whether a defendant has accepted responsibility for his acts, and the determination is entitled to great deference on review. Unless a court’s determination is without foundation, it should not be overturned on appeal.”).

Of course, these are only some of the most common types of cases where § 3742’s “due deference” requirement will require us to apply a “clear error” standard to district courts’ resolutions of mixed questions of fact and law involving the guidelines. As discussed earlier, the Supreme Court’s ruling in *Buford,*as well as our own holding in *Malgoza,*remind us that whenever a district court’s determination is best characterized as the application of a clear-cut standard to a complex set of facts, rather than a legal interpretation that can have broader value beyond the instant ease, “clear error” review is generally appropriate.

*12423. *Exception to the Two-Step Process of Review: “Dispositive” Factual Findings*— Some guidelines are fairly cut-and-dry; after reviewing the district court’s factual findings for clear error, it is rather apparent whether or not a particular enhancement applies. In these cases, the factual findings tend to be rather concrete and specific (e.g., the defendant either had a firearm, or he didn’t), or involve “lay” judgment calls that rely more on commonsense, everyday assessments than on specialized legal knowledge (e.g., did the defendant play a “major” or “minor” role in the criminal scheme).

Technically, of course, we must review a district court’s application of the guidelines to the facts, even in these cases. As a practical matter, however, once we come to a conclusion as to the district court’s factual findings, the question of the applicability of a guideline of this type practically answers itself. We frequently decline to specify a level of deference to accord the district court’s application of these guidelines simply because the issue is essentially moot — the factual findings all but determine the outcome. Thus, as a type of shorthand, this court often characterizes questions of these guidelines’ applicability as reviewable under a “clearly erroneous” standard. While the “clearly erroneous” standard technically applies only to the district court’s factual findings, those findings tend to be absolutely dispositive of issues involving these types of guidelines.

For example, in *United States v. Alred,*144 F.3d 1405 (11th Cir.1998), this court reviewed a district court’s ruling imposing an offense-level enhancement under U.S.S.G. § 201.1(b)(1) because the defendant possessed a firearm in conjunction with his offense. We noted, “We review a sentencing judge’s factual findings ... for clear error.” *Id.*at 1420. After upholding the district court’s finding that the defendant possessed a firearm in connection with his drug distribution, we had no choice but to affirm its imposition of a two-level enhancement under § 2Dl.l(b). *Id.*(‘We conclude that the facts that the district judge used as the basis for the section 2Dl.l(b)(l) enhancement were not clearly erroneous. Thus, [the defendant’s] enhancement for possession of firearms was appropriate.”); *see also United States v. Geffrard,*87 F.3d 448, 452 (11th Cir.1996) (“Possession of a firearm for sentencing purposes is a factual finding.”). There was no need to get into the requirements of “due deference” or to review the district court’s application of the law to those clear-cut facts. The court did not have to make any independent legal determinations or draw any further conclusions.

Similarly, in *United States v. De Varon,*we held that “a district court’s determination of whether a defendant qualifies for a minor role adjustment under the Guidelines is a finding of fact that will be reviewed only for clear error.” 175 F.3d at 934. We explained, “[T]he ultimate determination of [the size of a defendant’s] role in the offense is ... a fundamentally factual determination entitled to due deference and not a legal conclusion subject to *de novo*review.” *Id.*at 938; *see also United States v. Calderon,*127 F.3d 1314, 1341 (11th Cir.1997) (“[W]e review the district judge’s factual determination [concerning the size of the defendant’s role] for clear error.”). Of course, once we affirmed this factual finding (under the “clear error” standard), the question of a downward adjustment under § 3B1.2 (for defendants who play only a minor role) was essentially settled. Again, there was no need for either us or the district court to draw further legal conclusions.

This reasoning has also been applied on the other end of the spectrum. Determinations as to whether defendants played “managerial” roles have been treated as *1243questions of pure fact that do not raise questions about the pertinent guideline’s application and are reviewed under the clearly erroneous standard. *United States v. Glinton,*154 F.3d 1245, 1260 (11th Cir.1998) (“The district court’s determination is reviewed under the clearly erroneous rule.”).

It is critical to emphasize that this type of analysis — essentially folding our legal conclusions into the district court’s factual findings — is nothing more than a shorthand we use when we feel there is nothing to be gained by looking at a district court’s application of a clear-cut principle to a particular set of facts. In the majority of cases, however, there is usually *some*sort of legal determination to be made even after the fact-finding is done. As a result, our usual practice is to examine the district court’s application of the law to the facts separately, according this determination the level of deference it is due under § 8742 (as discussed in the previous sub-part). *See, e.g., United States v. Hall,*312 F.3d 1250, 1260-61 (11th Cir.2002) (applying a *de novo*standard of review in determining whether “the district court erred in failing to apply a four-level sentence enhancement under U.S.S.G. § 2G2.2(b)(3) (2001)” for trafficking child pornography that portrayed “sadistic conduct”); *Singh,*291 F.3d at 762 (reviewing *de novo*a district court’s decision to apply a two-level enhancement under U.S.S.G. § 2F1.1(b)(6)(B) “because a substantial part of the fraudulent scheme of which [the defendant] was convicted was committed from outside of the United States”); *Taylor,*88 F.3d at 942 (applying a *de novo*standard in reviewing the district court’s application of U.S.S.G. § 2A6.1(b)(l) for defendants who engage in “any conduct evidencing an intent to carry out [a] threat”). This line is admittedly indistinct and uncertain, but we are bound by our precedents and so must adhere to this doctrine.

4. *A Concluding Note about Upward and Downward Departures*— Of course, nothing in this opinion is meant to affect the manner in which we review district court rulings concerning upward or downward departures. “We review the district court’s discretionary refusal to depart downward only if the district court erroneously believed it did not have the statutory authority to do so.” *De La Mata,*266 F.3d at 1303; *see also Calderon,*127 F.3d at 1342 (“[Djownward departure is a matter of discretion that rests with the district judge and is ordinarily not appeal-able .... [W]e simply have no jurisdiction to review the district judge’s discretionary decision unless it was made based upon the belief that he did not possess such discretion.”). In contrast, “[w]e review a district court’s decision to [upwardly] depart from the Guidelines for an abuse of discretion.” *United States v. Melvin,*187 F.3d 1316, 1320 (11th Cir.1999). 18 U.S.C. §3742(e) requires that, when reviewing a district court’s decision to grant an upward or downward departure, we “review *de novo*the district court’s application of the [sentencing] guidelines to the facts.”

C. *Standard of Review for This Case*

Williams asks us to review the district court’s grouping of his offenses. Since this question clearly involves the application of the guidelines to Williams’s case, § 3742 requires us to review this question “with due deference” to the district court’s ruling. *See United States v. Bradford,*277 F.3d 1311, 1312 (11th Cir.2002) (“[T]his Court views the district court’s refusal to group multiple counts under § 3D1.2 with due deference.”); *accord United States v. Tillmon,*195 F.3d 640, 642 (11th Cir.1999); *United States v. McIntosh,*216 F.3d 1251, 1253 (11th Cir.2000); *United States v. Bonner,*85 F.3d 522, 525 (11th Cir.1996). Notwithstanding the implication of these cases — that “due deference” is either a *1244substantive standard in its own right, or a sort of modification on *de novo*review— the preceding discussion makes clear that “due deference” requires us to assess the type of question we are reviewing in order to determine the degree *of*respect to accord the district court’s findings.

Applying our *Malgoza*standard, the question of whether charges should have been grouped differently seems “primarily” one of law rather than of fact. We need not rely on the district court’s fact-finding, because the charges of which the defendant was convicted are clearly set forth in the indictment. To resolve this issue, we merely must interpret and apply § 3D1.2’s standards to these charges. Moreover, unlike *Buford,*this case does not involve an overly complex or unique fact pattern that will render our decision of little value in future cases. Thus, we need not afford the district court’s ruling any special deference, and we review its ruling *de novo.*

*III.*

Having established the proper standard of review, we now turn to the substance of Williams’s claims. He argues that Counts I and II — for conspiring to rob the armored car and attempting to rob the armored car, respectively — should have been grouped together under either § 3D1.2(a) or (b). We consider each section in turn.

A. *Grouping Multiple Counts Under § 3Dl.2(a)*

U.S.S.G. § 3D1.2(a) is not applicable because multiple crimes must be committed in the same general area and at approximately the same time to be- considered part of the “same act or transaction.” The guidelines provide the following example:

> The defendant is convicted of two counts of assault on a federal officer for shooting at the same officer twice while attempting to prevent apprehension as part of a single criminal episode. The counts are to be grouped together.... *But:*The defendant is convicted of two counts of assault on a federal officer for shooting at the officer on two separate days. The counts *are not*to be grouped together.

*Id.*§ 3D1.2, cmt. n. 3 (emphasis in original). In virtually all cases, a conspiracy is formed prior to the underlying offense it concerns, and in a place other than where that offense is to be committed. Thus, the formation of the conspiracy and the commission of the underlying crime are more akin to shooting the federal officer on two separate days than shooting him twice “as part of a single criminal episode.” *Id.*Only where the conspiracy and the underlying offense are roughly contemporaneous with each other — that is, when they are in both temporal and physical proximity with each other — are they part of the “same act or transaction” as contemplated by § 3D1.2(a). As we held in *United States v. Beard,*960 F.2d 965, 969 (11th Cir.1992), “the passage of time between offenses, differences in place of the offense, the nature of the offense, and the intervening circumstances taken together may justify separate grouping of the offenses.”

B. *Grouping Multiple Counts Under § 3Dl.2(b)*

Consequently, if Counts I and II are to be grouped together, it must be under U.S.S.G. § 3D1.2(b) (requiring counts to be grouped when they “involve the same victim and two or more acts or transactions connected by a common criminal objective or constituting part of a common scheme or plan”). The conspiracy to rob the armored car and the attempted robbery of that car were clearly parts of the same “common plan or scheme.” In fact, the attempted robbery of the armored car was the sole objective of the conspiracy.

*1245Thus, the only real issue is whether these acts involved the same victim. Inexplicably, the PSI concluded that these counts involved separate victims, stating “Group One [including only Count I] will represent the harm caused to Frank Gran-ja and Group Two [including only Count II] will represent the harm caused to Eshaman Ruiz.” This makes no sense. Count I was a conspiracy to rob the armored car; Count II was the attempted robbery of that car. It is impossible to claim that only Frank Granja was harmed by the conspiracy, while only Eshaman Ruiz was harmed by the attempted robbery. Both men were attacked during the robbery, and both were put in jeopardy by the formation of the conspiracy. The only reasonable explanation is that both men were victims of both offenses. Although as the government claims, multiple “counts arising out of a single transaction or occurrence [may not be] grouped together ... when there are distinct victims,” *see Brief for the United States,*at *10 (quoting U.S.S.G. § 3D1.2, cmt. background), the victims of the two offenses at issue here are the same. Consequently, the offenses are suitable for grouping under § 3D1.2.11 As a matter of law, a conspiracy to commit a substantive offense will almost always have the same victims as the commission (or attempted commission) of that substantive offense, and so the two should almost always be grouped together under § 3D1.2. This result is essentially mandated by the commentary to the guidelines, which states, “When one count charges a conspiracy or solicitation and the other charges a substantive offense that was the sole object of the conspiracy or solicitation, the counts -will be grouped together under subsection (b).” U.S.S.G. § 3D1.2, cmt. n. 4.

Thus, we do not contest the government’s claim that Williams’s conduct “resulted in ‘two separate victims.’” *Brief for the United States,*at *6. However, this observation does not allow the Government to separate two offenses that would otherwise be grouped together by arbitrarily “assigning” one victim to each offense where there is no clear basis for doing so. As discussed above, it is precisely because there were the same “two separate victims” for *each*of Williams’s offenses that we must group them together. If the Government wanted to punish Williams separately for the harm he inflicted upon each individual driver, it should have included two aggravated assault or attempted murder counts in the indictment.12

Our conclusion compels us to reject the notion, implicit in the government’s argument, that each offense can have only one “victim.” The Commentary to the Sentencing Guidelines states, “Generally, *1246there will be one person who is directly and most seriously affected by the offense and is therefore identifiable as the victim.” U.S.S.G. § 3D1.2, cmt. n. 2. While such commentary is binding on us, *see Stinson v. United States,*508 U.S. 36, 38, 113 S.Ct. 1913, 1915, 123 L.Ed.2d 598 (1993) (“[C]ommentary in the Guidelines Manual that interprets or explains a guideline is authoritative unless it violates the Constitution or a federal statute, or is inconsistent with, or a plainly erroneous reading of, that guideline.”), this particular statement is a broad generalization rather than an inflexible rule that must be applied in every single case. Where offenses such as the robbery and conspiracy at issue here equally harm multiple people, the guidelines do not force us to designate the “one real victim.” The main purpose of this provision is simply to emphasize that “secondary victims,” such as bystanders who may be traumatized at the sight of a crime, should not be counted as victims when grouping offenses under § 3D1.2. *See*U.S.S.G. § 3D1.2, cmt. n. 2 (“The term ‘victim’ is not intended to include indirect or secondary victims.”).

Consequently, Appellant’s sentences on Counts I and II are VACATED, and the case is REMANDED for resentencing.

SO ORDERED.

. Federal law provides,

> Whoever in any way or degree obstructs, delays, or affects commerce or the movement of any article or commodity in commerce, by robbery or extortion or attempts *or conspires so to do,*or commits or threatens physical violence to any person or property in furtherance of a plan or purpose to do anything in violation of this section shall be fined under this title or imprisoned not more than twenty years, or both.

18 U.S.C. § 1951(a) (1994) (emphasis added). The statute defines robbery as "the unlawful taking or obtaining of personal property from the person or in the presence of another, against his will, by means of actual or threatened force, or violence, or fear of injury, immediate or future, to his person or property, or property in his custody or possession....” *Id.*§ 1951(b)(1).

. The court also imposed a $300 special assessment against Williams, and ordered restitution of $404,080.29.

5

. *See supra*note 3.

6

. If two or more offenses are grouped separately, each group is assigned an offense level, and these individual offense levels will be considered in conjunction with each other to determine the defendant’s "combined offense level.” This combined offense level will typically be much higher than any of the groups’ individual offense levels.

If, in contrast, multiple offenses are grouped together, that group is assigned an offense level based only on the most serious charge it contains. The other offenses in that *1234group are essentially ignored and do not cause the defendant to have a higher "combined offense level.” Thus, it is to a defendant’s advantage to have as many charges as possible squeezed into as few groups as possible.

7

. The other circumstances under which multiple counts may be grouped together are not pertinent to the instant case.

8

. Because the statute is silent as to the standard of review for "pure” questions of law, we review them under our customary *de novo*standard. *See, e.g., United States v. Calderon, 111*F.3d 1314, 1339 (11th Cir.1997) ("In reviewing challenges to the application of U.S.S.G. § 3B1.3, we review the legal meaning of the term 'special skills' *de novo.”)*(internal quotations omitted); *United States v. Brenson,*104 F.3d 1267, 1287 (11th Cir.1997) ("[T]he question of whether conduct by a grand juror justifies the 'abuse of trust’ enhancement is a legal conclusion requiring a *de novo*review.”).

9

. This is essentially the approach for which the Government advocated in the instant case. *See Brief for the United States,*at *8 ("This Court reviews the district court's ... application of the sentencing guidelines *de novo.*Furthermore, this Court reviews the district court’s refusal to group multiple counts under USSG § 3D1.2 [sic] with due deference.”) (internal citations omitted).

10

. Perjury involves making a false statement "with the willful intent to provide false testimony, rather than as a result of confusion, mistake, or faulty memory.” *Singh,*291 F.3d at 763 (quoting *United States v. Dunnigan,*507 U.S. 87, 94, 113 S.Ct. 1111, 122 L.Ed.2d 445 (1993)).

11

. Williams’s attorney made this same point during Williams’s sentencing hearing:

> The probation officer's analysis fails because the probation officer concluded that one guard was the victim of the conspiracy and another guard is the victim of the robbery. That is clearly not what happened here. And as far as the conspiracy, either both guards were also the victim of the conspiracy or no one was the victim of the conspiracy. But [it cannot be argued that] one guard was ... the victim of the conspiracy and one guard was ... the victim of the robbery. That doesn't make common sense. The indictment charges one conspiracy with 2 victims. And the robbery charge, the indictment charges one robbery with two victims.

*Trans.*Apr. 3, 2002, at *4.

12

. It is possible, however, that aggravated assault charges would have been grouped together with the robbery. *See*U.S.S.G. ch. 3, pt. D, introductory cmt. (“Other offenses, such as an assault causing bodily injury to a teller during a bank robbery, are so closely related to the more serious offense that it would be appropriate to treat them as part of the more serious offense.... ”).
