I can't think of a way to prove it. What do you propose?

P.S. I admire your restraint in that response to my blatant dig.![]()
Well I think you would need a control group whom you could give a set amount of shots and measure their scratches and near scratches. Then you take some of them and teach them the method and test them again.
The point I was making moreover though is that a lot of people on here seem to really want pool to ONLY be learned through hitting a million balls and anyone who doesn't subscribe to that is seen as a talentless hack who has no chance to ever get to any decent level. My thought is that
The technique is the 45 degree angle into the rail off cuts to insure center table paths. Learning this reduces the chances of scratching tremendously and increases cue ball control immensely. It's a simple rule that is completely counter-intuitive for the "feel" players per my experience. But once learned it opens pathways previously either not considered or thought to be too cluttered for the cue ball to reliably sent through the clutter.
This is but one example of something learned through Dr. Dave's willingness to put it out there for anyone willing to study things that aren't obvious.
