You are simply over whelming yourself with these calculations using "center ball"
Okay. In that case...
Barring the truly supernatural, I would be very surprised to find anyone who is more accurate/precise in hitting the cue ball where they want to when favoring one side of the cue ball than when they are trying to hit "dead center".
For many pool players it's a natural tendency to want to spin shots in with outside "helping" English. This technique is very useful, especially if you're trying to change the natural angle of the cue ball after contact. There's another way to do this if you want to "master a shot" so you can hit the three parts of the pocket. To do this you must become more accurate and develop a "FEEL" for the pocket. This isn't any more difficult, it just requires you to simplify your Game and reduce calculations.
There are three {main} calculations you make to be accurate using "outside English," 1st) - you must judge the immediate deflection and 2nd) - you must judge how much the spin brings the cue ball "back" to it's original "shot line". 3rd) - you must decide where to hit the cue ball to accomplish the intended shot. (these calculations are related, but not necessarily connected like they are with the TOI Technique)
You will find it's necessary to hit these shots at a variety of speeds and a variety of spins to do what you need with the cue ball. This takes a LOT of different calculations because speed effects deflection AND spin. Where you hit the cue ball and how far over to get your "outside English" also effects deflection AND spin.
Over the course of hours, you will have to make numerous calculations and instinctive judgments to make every shot as planned. With the 'Touch Of Inside' system of play I am showing you how to reduce the amount of calculations and instinctive judgments considerably.
The TOI Technique shows you how to hit one "theme" of speeds, one "theme" of spins, and one "theme" of deflection. I have played many players in my life and the only concern I had was if they would play long enough. Because, even though this edge against other accomplished players may be only 1-2%, it will show up over time.
If you're cutting a ball at a "half ball" angle down the rail to the left and using "outside" (right English") you cue ball is immediately going to deflect into the object ball slightly. To overcome undercutting it you will need to spin the cue ball to make it curve back and the spin will help cut it in. This may "FEEL" like it's helping the cut, but IS IT REALLY?
You are having to hit the speed correctly, the spin correctly, the contact point (shot line) correctly and hit the cue ball precisely to do this. I'm sure you do this very well, but how about under pressure? How do you make all these calculations playing a champion player? This is where your unconscious will start to falter and break down.
You are simply over whelming yourself with these calculations and when you add pressure? I don't know, how does it effect you, do you play better or worse? How about over the course of a 5-10 hour set, do you rely on your game to get better and better or do you have "ups and downs?" With the TOI Technique I teach players how to use (as much as possible, of course there's exceptions, and less that you may think) ONE SPEED - ONE SHOT ANGLE REFERENCE (center or edge) - ONE TIP TARGET (the "Touch" of Inside).
The one thing you guard against {using TOI} is overcutting the ball, however, if you're going to miss a shot would you rather over cut it or under cut it? I don't know about you, but when I under cut a shot I feel like a "dogged it," however, when I over cut a shot I feel like I know what I need to do to correct what I did wrong.
