Matt is playing about the same he has played since he was 18 (I've known him since he was 13 or 14). He still can't beat Josh Brothers, who he grew up with, and Josh picks up a cue once a year now. The reason he wins all those tournaments now, is the top players in the Philly area all quit 10 years ago. He is the only one left, and he plays in every event. Now, Matt is a GREAT person, and a great player. I'm not saying a single bad thing about him. But ask the locals, he is about the same as he was 10 years ago. He didn't magically become a better player after learning CTE.
Brandon Shuff was on here that he learned CTE/Pro1 (or maybe you or someone else mentioned it, I forget) 2 or 3 years ago. He hasn't climbed the ranks. He's still a low to mid level US pro. He's never won a high profile tournament before CTE, and has not after CTE.
The other players you cite, were WORLD beaters as kids, before learning any aiming system. Guess what, they are still world beaters. But, they certainly did not jump to Efren level worldbeater after learning this system.
