If you believe center is 100% accuracy then I have to wonder what you're searching for. I think in your "heart of hearts" you "real eyes" this is a fallacy and hitting the center of the cue ball is like eating Tofu.
You will rarely understand why I get better feel and touch {by favoring the inside of the cue ball}, until a commitment to experiencing it. It's a huge advantage in my game and I think it's ironic after guarding the technique for so long that there's players that still doubt it's effectiveness.
Although after filming this new TOI Banking Video it's much easier for anyone to see how the angles are created with bank shots, sometimes the pocket is a "stumbling block," and keeps some players from seeing pocket billiards is simply creating angles on every shot.
Just like in golf, tennis, bowling and even baseball, there's more control and margin of error when curving the ball sightly with spin, only with pool, the ball's on the table so you must do it by favoring one side of the cue ball. The inside, if given a choice is the best because it cuts the ball more, not less, which maximizes margin of error in the pocket zone.
This enables you to align at one side of the pocket and accelerate the cue ball into the center, there's NO FEELING like creating zones in sports and games.....and of course I can explain this a thousand times and someone will rarely understand it until they experience it for themselves. When they do their game will increase exponentially, and enjoyment for the game will increase as a direct result of playing better, with real confidence.
It's like eating a particular food, I can describe it a thousand different ways, communicating as well as possible, and you still won't know what it tastes like until you commit the food to your own taste buds. Such is Life.
The Touch of Inside is a tad "salty".... certainly not "bland".
