Realistically talking here...most of the pistols you tested long term were capable of accuracy right around 2.5" or 3"...would it not be reasonable to assume that most production handguns are capable of that type of accuracy? Granted the M&P had some accuracy issues back in the day, but I'd say the go to guns for the majority of people on this forum (Glock, HK, SIG, Beretta, M&P, and GASP, the 1911) would meet that accuracy standard or at least be closer to 2" at 25 than to 4" right?
