Years ago I shot with a guy that was USPSA Master in all 5 classes. I was very impressed until I watched him shoot! He was a gamer, all of his classifiers were shot on his home range, every single one & he would cherry pick them & shoot them for a couple of weeks before their local match.
One of his friends told me in Revolver division (my division) that he always selected classifiers that required no reload & that he also shot minor power factor, so all he had to do was shoot "A" zone with his pop gun & he was Master class. I never once saw him enter any match shooting anything but limited or open class, depending on who would show up. There's a world of difference between IDPA & USPSA Master class.
After 10 pages it's pretty clear Ayoob is pretty controversial, except to himself.
