I appreciate what your saying and would like to try and maybe add some CTE to my game to get on the line...then use contact point? that the jist of one of your points?
That's pretty much the jist.... Consistency in finding the line and repeating the same motions to get there every time may be 75% of making ANY aiming system work.....
Usually you can watch how the players move around the table and are setting up into their shots and come away with an idea of who the favorite is.......
