You can't prove a negative. Someone can post a video of themselves, describing the steps to a CTE alignment, pull the trigger and miss, saying "see, I told you so"...but how would we know they were remotely lined up correctly? For that matter, I don't trust videos of people demonstrating it works, either. Someone has to apply the technique and system, then see for themselves whether or not it works. No way from a video can we perceive precisely what the other shooter is perceiving. If I see John Barton put cut out circles on a pool table, draw chalk lines depciting the shot line, the CTE line and using his cue to demonstrate the pivot, that just shows how to do it. Once he demonstrates a successful shot, who's to say what he really did? A player has to put in the work to understand and utilize the precepts of the system, to see if it works. Then, he's only proved it to himself.
