The shear fact that all these systems require you to make calculations and adjustments show that aiming is very subjective and there is no system that will put you in the right spot every time without using that very subjective eye to finalize the shoot any better than simply standing over the balls and making that determination on your own. Ultimately, that contact point still needs to be close enough to Point B that the margin of error for pocket acceptance is tolerable after your imperfect stroke. It is that subjective eye that determines your ultimate skill in the game. If it didn't, most of us here would never miss a shot.
CTE , TOI, Ghostball or whatever else out there is not going to increase your pocket margin of error and it certainly is not going to increase your stroke margin of error for contact Point A as it isn’t going to help you hit the CB on a perfect line. All those subjective things are still there regardless of the system used. What matters, as the original poster said indirectly, is that you hit the cue ball where you think you are hitting it over and over and over again no matter what “system” you use. I am simply pointing out that not a single system out there will physically make you do that based on their science. I am also pointing out that every system out there gives the disclaimer whether directly or indirectly that you have to “teach yourself” to adjust to what you see and have confidence in it. Why? Because that is them telling you to shoot it so many times that your mind’s eye is trained to hit the shot the way it needs to be hit using all the subjective input required including your flawed stroke. That ultimately is the bottom line of every aiming system ever invented or will ever be invented as the actual physics of making the balls will never change.
