Concentration, maybe try this:

Pool is total concentration and this might help you as it does me. Every morning, I have straight in shots corner to corner with the CB at x1, y2, and the OB at 3x, y6 for a straight in shot from corner to corner. Donuts set with a laser. I try to follow the CB into the hole with zero spin. I pick the middle of the rail ends (not the pocket) so the QB will follow straight into the hole. But after that drill, I pick 1-5 parts of the pocket (not really the pocket but the middle of the rail ends for a 3 the middle) and try to make the OB go into that part I've picked out. Shooting the OB into a 1 on the pocket, the CB will hit the end rail with a straight in shot. I can do it and it takes total concentration. Can you imagine playing every shot with this concept? My teaching pro always has and still does but it is concentration we may not be capable of without training. I'm not sure of what "aiming system" can do that.

I am practicing right now. But how many times have we missed a ball in hand shot? Total lack of concentration.
In my life I do not concentrate on any thing anymore since I retired. SO, playing pool for 3 hours, at our best, requires total concentration. What I've written about in the LP is the way to concentrate on every shot we take. I'm trying to learn it and maybe it can help others.

I'm not sure of what "stance system" or "stroking system" can do that, either. Concentration requires concentration systems, as you've outlined here.
