Both OB and Predator have close up pictures of their shafts including layered tips. One shows very clearly a few crumbs at the top of the tip, all that is left of the top layer after an install. If those layers are going to have much chance of lasting a chalking stroke that doesn't come from the outside inwards like you are trying to peel layers off is better. If you were trying to separate layers or damage the tip with the chalk, how would you do it? When you think about it that is exactly how many people chalk!
Without using a lot of spin, I generally chalk once between games and another time when I do need more than a tip or tip and a half of spin. That is once between games and once or twice in a game at most usually. If I just chalked recently I won't chalk between games. Bought a gross of Master blue for seventeen cents a cube years ago, that is gonna outlast me. I had collected a few pieces of flavor of the week chalk over a couple of years but I couldn't see trying to fix something that wasn't broken so I gave them to a friend.
As a serious competitor or gambler it is worth trying things that might give an edge but if there is no edge no sense putting the latest golden eagle on your cue. I have raced my own circle track cars, competed with fully custom rifles and handbuilt pistols, I'm not scared of spending money to be better but I can't remember the last time I miscued.

I've looked at the pics and agree with your theory.
Unlike you though, I chalk VERY OFTEN. Sometimes, I believe "chalking" is part of my PSR. It may be in my head but, it "seems" when I am in whatever gear i have.... i usually chalk way more than when I'm not at my best.
<<<<<<<<<< dunno, I'm still trying to figure out how to put a 1 pack together.
