I totally understand the posters angst about rule migration (changes), because I have been in same mood myself many times over the 25 years I have been shooting the sport.
I was upset when they changed the PF from 175 to 165 because I had tuned my gun and loads to that. I didnt like it when they approved turtle targets as I had spent a lot of time tuning my gun to track absolutely up and down. However, I think overall USPSA has done a great job and has changed rules so as to be more inclusive to more shooters and to allow modest innovation during the process. The idea is to push the limits of what practical becomes tactical. For example, how radical was the first red dot that is now on many defensive, LEO, and military shooters. Many common pistol features today started out in USPSA. Ours is not a static sport, it changes and should allow improvement .Otherwise we would all be shooting 1911 Single Stack .45 and there would be fewer competitors.
