I care only in regard for helping others play better pool. What I don't care about is the 20yr war on whether or not CTE is objective or whether or not it works exactly as Stan describes it. I believe people are capable of reaching their own conclusions. I don't think pool players as mindless idiots in need of internet wizards to guide them one way or another when it comes to what might be beneficial to their game. That is something each player must discover for themselves.
Concerning how to use which eye to obtain the perspective you want or need.... I don't know how to do it, not do I care about learning how to do it.
And no, I don't think Stan's CTE provides a center pocket shot line for each shot. This is just my opinion, based on the fact that there are several CTE perceptions used, and each one has its limits. In other words, a 15 outside works to pocket a straight in shot. If you move the ob a little to the left or right, the 15 outside still works. If you move the ob too far left or right, the 15 outside will no longer work and a 15 inside must be used. That tells me that when using the 15 outside for each angle farther and farther away from straight in, the ob is landing farther and farther away from center pocket. And when the limit of the 15 outside is reached, it's time to change to a 15 inside.
I realize Stan and other CTE players will disagree with this, but I don't care. They've conditioned to believe what they want, and I have been conditioned to believe what I want. It means nothing to me that we believe different things. It's not something I feel the need to argue about because it's irrelevant to me.
