Hit Cap less than orginally thought?

WoW players frequent Elitistjerks.com, a forum that has quickly become a pseudo-Mecca for WoW Theorycrafters. Pages of arguments have been made on every topic imaginable; DPS, healing, tanking, professions, everything mathy in WoW is up for debate. In fact, some raiders take anything on “EJ” as gospel simply because of the source.
The topic de jour amongst the physical DPS folks is a possibility that the hit cap may be lower than originally thought. Tests by several individuals, a majority of them hunters, have run tests on Patchwerk, Heroic Dummies in town, etc.  They show zero or few misses with ranged and melee weapons with just 8.02% additional chance to hit. Results with 7.89% chance to hit show 1 or 2 misses over a thousand shots.
