You raise some extremely on point questions, PJ. I can only give my opinion on WHY I think Cte works, without any written backup. Others may dispute my claims, but from experience I've seen an extended view and now am coming to understand Stan's comment on "higher levels" of aiming.
He gives us a hint of what I'm seeing in my game in his dvd. He talks about what a pro player sees when he asks what he sees when he is shooting a shot (I'm not a pro). He also mentions the fact that now that this information is available, a lot of upper level players are going to dial in their games with it. This not a hype for sales (it didn't hurt though :wink

. It was a seminal observation that made me contort and become uncomfortable because it was true.
I, for one, am happy for Stan and wish him well with his sales. He is the mentor of Pro One and deserves success after his hard work. On the other hand I wish I could keep all the candy for myself and not feed the fish.

I'll be getting knocked out of tourneys now and with my own system!
Cte is not a system that shows you WHERE to find the contact point, but instead shows you HOW to find the contact point. No other system does this. Some have surmised to an obvious conclusion that it develops your pre-shot routine. Why? Because you are letting your eyes arrive at a position that lets them aim correctly. How valuable is this fact?
Early users think they are lining up their bodies to point at the shot line. If you stand this way, you can make all shots. You are now pointed in the right direction. Yes and no. When your eyes are lined up correctly you will line up physically better. Cte is teaching you where to line up with your eyes, then your body.
This diligent practice with Cte and then Pro One reinforces correct eye alignment and over time will morph into an automatic shooting alignment. I typically use no pivot, no selective bridge length, no reference points. My mind has assimilated the process and they are not necessary anymore. If I slump, I double check things with Pro One. If the shot is low percentage or pressure has me tight, I can use Pro One to double check myself. I warm up with Pro One and get in stroke quickly as my visuals dial in.
Cte works by dialing in your visuals. A progression to Pro One connects your body to the natural equation. Joey A mentioned in another thread how he just got down and shot at his last tournament without any system. He is moving into the next stage of aiming because he has finally learned after years of playing where his eyes need to be. I know this feeling and am trying to pin it down on paper. Right now I can't. All I really am sure about is that I have finally learned where to put my eyes and am improving my game at a steady pace in the last few months. This is the reward for learning Cte when it was so easy to quit.
Best,
Mike
