## Background
CLAIM OF PRIORITY
This application claims priority to and the benefit of Provisional Patent Application No. 62/390,422 filed Mar. 29, 2016.


BACKGROUND OF THE INVENTION
Technical Field
The present invention relates to systems and methods establishing and arranging ability groupings for participants in certain equine competitions based on a Past Performance Indicator (PPI). Ability groupings are established in equine events in order for contestants, including their equine, e.g. horse, to compete against others of the same or similar capability. Horse/rider contestants are assigned to an ability group based on their PPI, which is calculated based on results from their prior events. The systems and methods disclosed herein can be used for equine speed events as well as judged events. A preferred embodiment of the presently described system and method is an equine sporting event that is a speed event called barrel racing.
Description of Related Art
The event of barrel racing draws many contestants. In a barrel race each contestant rides a horse around a pre-defined path of three spaced barrels in a triangle pattern, such as that shown in FIG. 1. The goal of the horse and rider in such a race is to complete the course in the shortest amount of time possible. The time it takes from when the horse interrupts a photoelectric light beam until it finishes the pattern and again interrupts the same light beam racing out of the arena is their run time. One of the ways that barrel races are conducted is that each contestant competes against every other contestant and the fastest finishers win a prize, typically in the form of cash. Depending upon the size of the field of competitors, the producers of the event may award cash prizes to only the one horse and rider pair with the fastest time or some plurality of top finishers.
Another method that allows for more contestants, separates the run times of all horse/riders after they have competed in the race into 4 or 5 groups or splits of run times called divisions. The contestants having the fastest run times in each of these splits wins their division. While this pits contestants, including their horses, against only those with similar run times, it does so after the barrel race has been completed. It would be far more fair, interesting and sporting if each contestant (i.e., rider) and/or equine competed with others having similar capabilities and records based on results of previous events. That is, the division and assignment of events pitting competitors of similar abilities against each other occurs before the start of race, rather than aligning contestants after races begin.
Other types of equine sporting competitions are judged to determine how well contestants and/or horses perform during an event. Most of the judging competitions today are divided using classes of competitors including classes for junior, novice, amateur, senior, non-professional, professional and others. There is a need, therefore, for systems and methods to appropriately categorize, assign and group competitors in both timed and judged equine events according to the contestants' respective ability levels.

DETAILED DESCRIPTION
Several embodiments of Applicant's invention will now be described with reference to the drawings. Unless otherwise noted, like elements will be identified by identical numbers throughout all figures. The invention illustratively disclosed herein suitably may be practiced in the absence of any element which is not specifically disclosed herein.
The presently described equine competition event grouping system and method rely on ability comparisons of competitors based on past competitor performance in order to create groupings or sets of competitors of substantially equal abilities. The presently described ability groupings are determined based on a Past Performance Indicator (PPI), which is used to determine a competitor's event-related ability based on prior performance data. Barrel Racing Ability Grouping Sport (BRAGSTM) is a novel competitive format used at barrel racing events to promote and facilitate barrel racing among competitors of similar racing ability. To be placed in an ability group prior to an event, contestants (equine and rider) competing in an equine event, such as a BRAGSTM event must have a PPI. Because the horse's speed results in prior events are a good determinate of its athletic ability, the preferred PPI for speed events is the horse's run speed (feet/second) from prior events. This speed, or Run RateTM reflects its average speed maintained during a plurality of prior barrel races or runs. Once all contestants are entered, their converted Run RateTM or Run Speed IndexTM (RSI) is used to formulate ability groups of substantially equally matched horses and riders. Thus, each contestant will be competing against only the contestants with similar ability. Before a race begins, the competitors will know whom they will be competing against, and prizes and/or prize money will be awarded in each ability group according to the fastest time, second fastest time, etc. The prize payouts, in one embodiment money prizes are calculated to allow all contestants to have the same odds of winning. The present method and system of leveling the odds or probability that contestants of different ability levels can win a barrel race encourage more racers to enter and compete and at the same time draws more interest among spectators.
This format relies on contestants' PPIs to establish ability grouping thus allowing all levels of equine event contestants to compete with others in equally matched groups based on prior performance data. Although barrel racing is the preferred described sport, the Barrel Racing Ability Grouping Sport (BRAGSTM) method can also be used for other well-known speed events including, but not limited to, pole bending, flag racing, and straight barrels. Similarly, ability grouping can be used at judged equine events including cutting, reining, reining cow horse and hunter jumper in order to subdivide classes into smaller groups based on prior event scores. Contestant/horse entries must have PPI to group contestants within their event classes. For judged equine events, the preferred PPI will be the average of judged scores from prior events. In another embodiment the PPI may be a function of additional data. Classes, therefore, can be subdivided based on the ability of horse/rider combination. By utilizing past judging scores to determine a PPI for each contestant and then ability grouping the contestants and/or equine, some of these classes can be eliminated and/or combined by allowing riders to be grouped together based on judging scores from prior events.
According to one embodiment, if a contestant and/or equine does not have any, or enough, prior performance results to determine a PPI, that competitor will nevertheless be allowed to compete under review. In such an instance, the competitor's current event speed or judged score is used to assign the competitor to an ability group. Along with the performances of the others in that ability group, winner(s) are determined.
In operation, the presently described equine ability grouping systems and methods are employed to organize and enhance barrel racing contests in rodeos, jackpots and other events. In order for contestants and/or equine competing in a BRAGSTM event to be placed in an ability group prior to the event, their respective ability levels must be determined based on prior performance data. Prior performance data is used to determine each contestant's PPI, which is used to draw contestants into ability groups. A horse's speed results in prior events is a primary indictor of its athletic ability and is, therefore, the preferred variable used to determine the PPI. The horse's run speed from prior events will be referred to as Run RateTM or Run Speed IndexTM (RSI). In other embodiments, however, PPI can be based on one or more other data points, including, but not limited to, the contestant's riding ability, run consistency, split rates, age, prior winnings, entry-to-win ratio, return on investment, classification, and the like.
In one embodiment, a contestant's/horse's Run RateTM or RSITM is calculated according to the following process. First, the horse's running speeds or event rates (ERs) from prior races are calculated for a number x of previously entered events, rodeos, etc. To calculate the ER for a single event the pattern distance (PD), which is the total number of feet a horse travels during a race, and the run time (T) in seconds spent to complete the pattern are determined. In a barrel race, competitors race in a clover leaf pattern around situated barrels. FIG. 1 depicts a typical barrel race course 100. An embodiment of race course 100 includes three barrels or other objects that a rider and horse pair must navigate during the race. These barrels are arranged in a triangular pattern so as the pairs travel the course, they form a clover-type pattern.
As shown in FIG. 1, a first barrel, a second barrel and a third barrel are arranged at points 106, 104 and 102, respectively, in an isosceles triangular pattern. Each horse and rider pair starts the timed event at timer line 110. Timer line 110 can be equipped with a light beam activated timer as is known in the art in which the timing of a pair's run starts when the sensor associated with the light beam is interrupted and stops when the pair crosses the time line again and disrupts the light beam again. As shown, the horse rider pair travel a path 140 around each of the three barrels at locations 106, 104 and 102. In a standard barrel race course, first barrel 106 is situated a distance 130 from second barrel 104. Second barrel 104 in turn is placed a distance 120 from third barrel 102. In a standard course 100, distance 120 is approximately 105 feet and distance 130 is approximately 90 feet. The PD for a standard barrel pattern 100 as shown is 453.142 feet when a rider and horse pair follows path 140. The more efficiently or tightly the pair can navigate barrels 106, 104 and 102, the shorter the actual path of travel, which translates into a faster course completion time.
Because some rodeo venues or arenas cannot accommodate a standard pattern as shown in FIG. 1, barrel patterns will have varying pattern distances depending on the arena size. Therefore, all ERs are standardized or adjusted along a standardized slope (SS) to a Common Pattern Distance (CPD). In one embodiment, the preferred SS is 0.02152 as determined by performing a linear regression of prior PDs and corresponding run times in a linear regression calculation. This SS factor, however, may increase or decrease as additional data becomes available and a more accurate slope is calculated. The SS is determined by graphing results from hundreds of run times and their corresponding PDs (not only from an individual horse/rider pair). Using this large number of data points enables determination using linear regression of a standardized slope, that is, a standardized relationship between a run time and a PD.
Once the SS is determined, a contestant's ER for each previous race is determined based on the formula:

ER=CPD÷[((CPD−PD)*SS)+T]

In the above formula and throughout this disclosure, an asterisk (“*”) denotes the multiplication operation. The above formula is used for all ER calculations in order for each ER calculation to be standardized according to a common pattern distance CPD. Note that the PD is calculated for each different arena because the actual pattern measurement for each arena will vary. Also, CPD is preferably 400 feet, but can be increased or decreased. Run time, T, used in the calculation preferably does not include any penalty seconds added to a contestant's result from a prior event, as such penalty seconds tend to not be indicative of ability.
Once all ERs are calculated from an event in the manner described above, the ERs are analyzed to determine whether the results may be skewed or anomalous due to factors affecting a particular event beyond the contestant's control, such as poor arena ground conditions, an overly difficult arena set up or other extraordinary conditions. If the results from a barrel race or rodeo are determined to be anomalous, that event will not be used for determining Run RatesTM. The process to determine if ERs are skewed or anomalous due to adverse or extraordinary conditions includes a comparison of the speed of horse/rider pairs at the event in question with the run rate upon entering the current event. This comparison is referred to as the Run Gauge (RG). Run Gauge is indicative of a horse/rider's success at an event. If the average Run Gauge from all contestants is low it indicates an outside factor or condition that led to the out of the ordinary result. This process of determining Run Gauge is described below.
For each horse/rider pair that is competing in an event, a list of RGs is created. For each horse/rider pair, the RG is the ER less the pair's current Run RateTM, or RG=ER−RR. Then, for each pair if the RG value for a particular race is greater than or equal to −3.0 feet per second (RG>=−3.0 ft./sec.), the event is included in the RG calculation. If RG<=−3.0 ft./sec., then that race result is excluded from the RG calculation. Any RG values discarded at this step are not used in the Run Rate calculation for a horse/rider pair.
Once any low RG values are excluded, an average of the remaining RG values is calculated. If the average RG value is greater than negative 1.0 (A>=−1.0), then there is no evidence that the race has skewed results and all Event Rates from the event can be used in RR calculations. If, however, A<−1.0, that is, on average event times were much slower than the horse/riders capability, all ERs from that event will be discarded and not used in Run Rate calculations. Although −1.0 is the preferred value used to determine if particular race results will be discarded, this value can be increased or decreased as more data is collected.
Next, the horse/rider pair's RR will be calculated from their prior ERs. This calculation is performed according to the following steps, with X being the number of ERs for the horse and rider pair. The preferable minimum value for X is at least five (5). If X is less than five, the pair's RR will not be calculated. However, the minimum number of ERs (5) used in calculating a pair's RR may increase or decrease.
If X>=5, then ERs are sorted according to competition date in descending order and only the top N ERs are used, such that 5<=N<=20. For each remaining ER, those that had a Run Gauge (RG) greater than one foot per second (RG>1.0) are counted twice in the following step (added as an additional ER). These ERs are doubled or counted twice because they are considered “exaggerated event rates” that are substantially faster than the pair's current RR.
RR is calculated by taking the better half average, that is calculating the average of each pair's top N÷2 (integer division) ERs. For example, if a horse/rider pair has five ERs of 25.2, 25.0, 24.8, 24.6 and 24.4, only the top 5÷2=2 ERs will be used to calculate the Run RateTM RR. Thus, the calculation will be:

RR=(25.2+25.0)÷2=25.1

Finally, the pair's RR is converted to a Run Speed Index or RSITM for easy understanding. Various scales can be used for RSITM calculations. The preferred 10 point scale for converting RR to RSI value is determined by RSI=10−(26−RR). However, other scales can be used such as a 100 point scale, determined by RSI=100−((26−RR)/0.1).
Note that when a horse/rider pair wishes to enter a BRAGSTM event before accumulating sufficient ERs, (preferably 5) to calculate an RR, the pair can be allowed to run “under review”. This means that the pair will be allowed to compete, but will not be drawn into an ability group prior to the event. After the event, however, the pair will be “post-grouped” into an ability group using their ER to determine their “G” (ability group, G, see below). This specific ER will be recorded and used along with their prior Event Rates in the RR calculation for their next event.
Ability Groupings
Once all barrel racers are entered at a BRAGSTM event, contestants with current RSIsTM calculated as described above will then be drawn or placed, into substantially equally matched ability groups. These ability groups, or Gs, will be formed using statistical analysis of the RSIs for all entered horse/rider contestants. One embodiment for grouping the rider/horse pairs is depicted in the ability groupings plot 200 of FIG. 2. As seen in FIG. 2, the ability grouping process starts by determining the mean RSI then moving outward. The ability groups shown in FIG. 2 are designated group 1G 202, 2G 204, 3G 206, 4G 208, 5G 210, 6G 212, 7G 214, 8G 216 and 9G 218. The x-axis or horizontal axis 230 of ability groupings plot 200 represents the beginning and ending range of each ability group's RSI value and the y-axis or vertical axis 240 represents the number of entrants in each ability group. The fastest ability group is 1G 202, the next fastest is 2G 204 and so on. The number of ability groups will vary depending on the overall range of RSIs entered at the event. In the ability grouping plot in FIG. 2 for a barrel race, there are nine groupings (Gs) of contestants. A preferred range of each ability group or Group Range (GR) is calculated based on the standard deviation (SD) according to the following rules.
If SD>=1.0 then GR=0.5
If 0.6<=SD<=0.9 then GR=SD/2 (integer division)
If SD<=5.0 then GR=0.2
GR may also be estimated at a value of 0.5 or can be reduced (narrowed) or increased (widened) by the barrel racing producer depending on the number of ability groups desired. A preferred minimum number of contestants drawn into an ability group or minimum group count (MGC) can be determined based on the following rules:
For 50 or fewer entries, MGC=3
For 51 through 120 entries, MGC=5
For more than 120 entries, MGC=4% of the number of entries
The minimum group count (MGC) can also be adjusted upward or downward by the barrel racing producer. As seen in FIG. 2, for the ability groups formed at a typical barrel racing event each contestant only competes against barrel racers in the ability group in which they are drawn into. That is horse rider pairs within 1G 202 compete against only those pairs within 1G 202. Horse rider pairs within 2G 204 only compete against only those pairs within 2G 204 and so on. The fastest race time in each group will be declared the winner of the ability group. The next fastest time will be second and so on. In this manner, racers of every ability level are incentivized to compete. No horse and rider pair will be assigned to more than one ability group.
A method performed according to an embodiment of the presently described system of establishing the ability groups at a BRAGSTM event is shown in the flow diagram of FIG. 4. The method of FIG. 4 begins at step 402 where the RSITM values corresponding to a group of race entrants are sorted from fastest RSI time to the slowest RSI time. Next, at step 404, the mean RSI value is determined for all competitors entered in the event. Then at step 406 the process continues with a determination of the standard deviation of the RSI values for all of the competitors entered in the event. Step 406 can be completed according to a well-known manner of standard deviation calculation.
At step 408 the process continues with selection of a Group Range (GR) according one of the rules described below. In one embodiment, if SD>=1.0, then GR=0.5, but if 0.6<=SD<=0.9, then GR=SD/2 (integer division). If SD<=5.0 then GR=0.2. Next, at step 410 the upper and lower limits of the middle ability group among the groups are defined. In this step, one half of the Group Range (0.5*GR) is added and subtracted from the calculated mean RSITM from step 404. These values then serve as the upper and lower limits of the middle ability group, e.g. 5G 210 in the chart of FIG. 2. At step 412, two additional ability groups are drawn by adding and subtracting the Group Range to the upper and lower ability group limits of the upper and lower limits of the middle ability group defined in step 410. In this step, second and third ability groups 4G 208 and 6G 212 as shown in FIG. 2 are defined.
The process continues at step 414 where the system queries whether all race pairs have been included in an ability group. If the answer to this query is “no”, the process repeats step 412, but next defined ability groups are based on the upper and lower limits of the last defined ability group(s). As seen in FIG. 2, groups 3G 206 and 7G 214 would be the next groups defined. If, on the other hand, the answer to query 414 is “yes”, the method moves to step 416 to determine the minimum group count (MGC). In a preferred embodiment, the minimum group count (MGC) is determined, where for 50 or fewer entries, MGC=3; for 51 through 120 entries, MGC=5; and for more than 120 entries, MGC=4% of the number of entries. Once the MGC is determined, the process continues with step 418 where the system queries whether at least one group is fewer in number than the MGC. If the answer to this query is “yes”, the at step 420 the lower and upper RSI values of the ability groups are adjusted so that all group sizes are greater than or equal to the MGC. For each group having fewer entrants in number than the MGC, if the ability group is a lower numbered ability group (meaning a group having higher ability to left of the ability group containing the mean RSI), then the lower limit of the ability group at issue is decreased in one tenth (0.1) increments until (a) the MGC is reached and (b) the next contestant's RSI is not a duplicate. Next, the upper limit of the next G is adjusted at step 422 so no overlap occurs.
If, on the other hand, the ability group is higher numbered ability group than the mean ability group (meaning a group having lower ability to right of the ability group containing the mean RSI), then the upper limit of the ability group at issue is increased in one tenth (0.1) increments until (a) the MGC is reached and (b) the next contestant's RSI is not a duplicate. Then, the process concludes at step 422 with the lower limit of the previous G is adjusted to eliminate overlap of adjacent ability groups. Note that either of these steps within step 418 may cause an adjacent ability group to fall below the MGC. If this occurs, the steps above are repeated until all groups sizes are greater than or equal to the MGC.
FIG. 5 depicts eight ability groupings 502. Each grouping 502 is centered around an average RSI value 504, and the group range GR is set based on the standard deviation of the RSI values. As shown, for group 4G, its RSI range includes the average RSI value 504, and upper limit 506 and lower limit 508. The next created ability groups 3G and 5G have their upper and lower limits established. Group 3G's upper limit 510 and lower limit 512 are shown as are upper limit 514 and lower limit 516 of group 5G. Similarly, in FIG. 6, eight ability groupings 602 are shown. In FIG. 6, however, each ability grouping 602 centers around an average RSI value 604 that resides in ability group 3G. Group 3G includes upper limit 606 and lower limit 608 and neighboring ability group 4G includes upper limit 601 and lower limit 612. The group range GR again is based on the standard deviation of the RSI values.
Following the process described in FIG. 4 group entrant payout is determined, as will be discussed below.
Determining Ability Group Payout. The number of places to be paid in each ability group or places per entry (PPE) is determined by the number of contestants in each ability group. By paying one place for every B barrel racers in the ability group, the odds of placing will be the same for all barrel racers entered no matter which ability group into which they are drawn. For example, if a producer chooses to pay one place for every ten barrel racers in each Group (PPE=10), the odds of winning will be 1:9 for each barrel racer. A “proportional” method will be used to determine the amount of prize money for each winning position using the following steps. First, the total amount of prize money (PM) to be awarded at the competition is determined. Next, the PPEs that will actually be paid out is selected. Then, for each ability group the number of places that will be paid (PP) is determined by dividing the group size by the PPE, where L is the largest number of places paid (PP). Next, for each ability group a “Matrix Percentage” (MP) is determined according to MP=PP/(Group Number*L). Thus, the lower the group number, the higher the percentage of the total prize money paid for that group as compared to higher numbered groups.
Then, for each ability group the group percentage (GP) is calculated according to the following formula:

GP=MP/S 

where S is the sum of all the Matrix Percentages (MPs). Next, the total amount of prize money available for each ability group (G$) is determined according to

G$=GP*PM

Finally, for each specific ability group, the prize money available for each place within the ability group is determined based on the prize factor table 300 shown in FIG. 3. For each place within an ability group, G$ is multiplied by the factor in FIG. 3 that corresponds to a place of finish. Various places paid factor 310 represent the number of finishers in an ability group that will receive prize money. The total of each vertical column of places paid factors is 100, representing 100 percent of the prize money for that group. In prize factor table 300 includes values for an ability group having three entrants eligible to receive a prize. Note that in such a group, the places paid factors in the column bearing the heading “3” total 100. The places paid factor for the third finisher eligible to receive prize money in a group in which three entrants receive a prize is 16.69, found at location 320 of prize factor table 300. That is, the third place finisher in a group having three entrants eligible to receive a cash prize will receive 16.69 percent of the prize purse for that ability group. The places paid factors in FIG. 3 represent only one embodiment and the individual prize money available may be increased or decreased depending on the barrel race producer's preference.
The following examples demonstrate the ability groupings, modifications and payouts determined by employing the methods described above for a given barrel race, or other similar contest.
Example 1
The following is an example of the payout at a barrel racing event according to the aforementioned protocol. This example assumes that the barrel race producer will pay one place for every seven contestants (PPE=7) in each ability group and that the barrel race had 104 entries, with each contestant paying an entry fee of $35. The total amount paid out to the winners is 75% of the total entry fees collected.
Based on these assumptions, the total amount of prize money PM to be awarded at the competition is:

PM=104*$35*0.75=$2,730

With the selection of PPE=7, the number of places to be paid (PP) in each ability group is determined by dividing the group count by the PPE and rounding up to the nearest integer. Therefore,

PP1=24/7=3.4=4

PP2=17/7=2.4=3

PP3=27/7=3.8=4

PP4=15/7=2.1=3

PP5=14/7=2.0=2

PP6=7/7=1.0=1

For each ability group, the Matrix Percentage (MP) is determined such that

MP=PP/(Group Number*L)

where L is the largest number of places paid for PP1 through PP6. In this example, as seen above, L (PP1)=4, so for PP1 through PP6, the MP is

MP1=4/(1*4)=1.0000

MP2=3/(2*4)=0.3750

MP3=4/(3*4)=0.3333

MP4=3/(4*4)=0.1875

MP5=2/(5*4)=0.1000

MP6=1/(6*4)=0.0417

Next, the sum S of all of the MPs is determined.

S=1+0.3750+0.3333+0.1875+0.1000+0.0417=2.0375

For each ability group, the Group Percentage (GP) is determined by

GP=MP/S 

such that

GP1=1.0000/2.0375=49.08%

GP2=0.3750/2.0375=18.40%

GP3=0.3333/2.0375=16.36%

GP4=0.1875/2.0375=9.20%

GP5=0.1000/2.0375=4.91%

GP6=0.0417/2.0375=2.04%

With each GP known, the total amount of prize money (G$) to be paid out in each G is

G$=GP*PM

where the resulting G$ for each group G, rounded down to the nearest dollar, is

G$1=49.08%*2,730=$1,340

G$2=18.40%*2,730=$502

G$3=16.36%*2,730=$447

G$4=9.20%*2,730=$251

G$5=4.91%*2,730=$134

G$6=2.04%*2,730=$56

Next, places paid factors, such as those shown in FIG. 3 for four entrants in an ability group are used to determine the prize money for each placing entrant (all amounts are rounded down to the nearest dollar). For the ability group 1G the prize money awarded is:

    
    
        1st place—$1,339*40%=$535
        2nd place—$1,339*30%=$401
        3rd place—$1,339*20%=$267
        4th place—$1,339*10%=$133

Table 1 below shows the payout for all of the six ability groups according the process described above.

Example 2
In this example, 119 contestants entered at BRAGSTM barrel racing event. The average RSITM for all entries is 7.9 and the standard deviation is 0.8. FIG. 5 depicts the upper and lower limits of each ability group that are calculated based on a Group Range (GR) equal to half of the standard deviation (GR=0.8*0.5=0.4)
Table 2 below reflects the starting/ending RSITM values, number of contestants and Group Range for each ability group 1G through 8G based in accordance with the groupings shown in Table 1, above. Note that the 8G ability group is less than the preferred minimum group count (MGC) of five contestants.

Example 3
In this next example, 142 contestants are entered in a BRAGSTM barrel race. The average RSITM for all entrants is 8.2 and the standard deviation is 0.8. FIG. 6 depicts ability groups 1G through 8G that are drawn using the preferred size of ability group (Group Range) one half (1⁄2) of a standard deviation. As seen in FIG. 6, ability groups are formed by beginning at the mean (8.2) and moving outward.
Table 8 below shows the starting/ending RSITM values, number of contestants and Group Range for each ability group, 1G through 8G based on the values derived as depicted in FIG. 6. Note that the 7G and 8G ability groups have less than the preferred minimum group count, MGC=4%*142=6.
