You know what, since the last exchange Oakster has clarified a source on the page, and he has also reverted you. Make the argument with him, or take it to the project page. 
The sources clearly show the following; The Triple Crown was defined with Pedro Morales WWF title, WWF IC, WWF Tag. Then HBK expanded it to GSC, to include the Euro. Then Kurt Angle expanded it to include the SD Tag titles. Then HBK and HHH expanded it to include the WHC. So Tier 1 (WHC, WWE) Tier 2 (TT and SD TT) Tier 3 (IC not US) and Tier 4 (Euro). Then Kane expanded it to include HC on Tier 4. If anyone has any combination of those seven titles then they are a Grand Slam Champion. Even if tomorrow WWE.com were to announce the TCC and GSC never happened it would not change a thing. 
The point about Benoit is that WWE.com is not 100% reliable. They do change their minds (did the Rockers ever beat the Hart Foundation, no for about a decade then yes once Bret Hart left and they rewrote history). AT the moment the WWE do not acknowledge the existence of the 2004 RR winner, so does this mean we erase it from Benoit's article? No. The expanded definition for the GSC and TCC still stand, and as HBK never even wrestled for WWF/WWE while the HC title was active I have no idea why his bio would ever talk about the HC title. (He was retired from March 1998 to SummerSlam 2002 the exact length of time the HC title was active.) 
If you have a problem with my revert then gain consensus for your view of the events, at the project talk page or ask Oakster why he agreed with my revert.
