According to Stan Shuffett, you see both lines at the same time, not one then the other, and not standing directly behind any one. That is exactly what I am doing.
I started with straight in shots, using a 15-inside or 15-outside, and it works. I used a 10" bridge distance, came in parallel to the CCB line initial given by the perception, 1/2 tip left or right for inside/outside pivots. I set up the exact shots Stan shoots in a few videos where he says the 30-outside is the same as a 15-inside, and that's when you know a shot is thin enough to be moving out of the 15 and into the 30 perception. I have no problem doing this. The bridge distance affects the offset angles (thin or thick) generated by the pivot -- a longer bridge creates finer thinning or thickening angle. The distance between the balls affects the perception you get from the visuals. CTE and ETA lines with 1 diamond distance between the balls will provide a different CCB perception than a CTE and CTA at a 3 diamond distance.
What I find odd is that all of this can be proven with math on paper, yet no one has posted anything on it that shows how or why it works. And still I am told that I am way off. How would anyone know whether or not I am wrong if no one can explain or show how it works?
But I'm fine with waiting on the book. CTE's been out 10+ years already, so a few extra months isn't that much longer to wait. It sure beats dogmatically duking it out with fellow pool players over how something works, especially when so many admit to not knowing how it works.
