My favorite claim is all the, "well this pro actually does use an aiming system he just doesn't realize it, but if you break down his game he clearly is subconsciously using MY aiming system that I teach for $4,000 if you travel 600 miles for a two-day clinic"
Pool balls are relatively inelastic and have low friction so figuring out how to impart a net force vector pointed at the pocket is very very easy, you just hit the CB so it contacts the object ball 180 degrees away from the pocket, with minor adjustment for throw when required. I don't know how or why people dream of ways to make this so goddamn complicated.
Trust your brain to correctly calculate the CB's size and visualize the contact point and with even a tiny bit of experience, as long as you pay attention, you'll be automatically compensating even for high spin effects, and soon the possibility of even missing an open shot will seem absurd to you and you'll only be worried about controlling that CB into perfect position every time. If your brain is not naturally blessed with a good perception of spatial relationships, masses, forces, etc., you'll have to work on developing that feel but breaking it down into a completely verbally-communicable thought process is not how you get there, running racks will be mentally exhausting if you don't internalize the physics of the game at some point.
