dpp: I guess I can accept that
I didn't show the 2 inch miss because I'm working on the assumption that on the worst day of the shooter's life, he can't miss the ball by that much. If the worst day of his life is a 2 inch miss, then it's the exact same situation: He can overcut really badly by 2 inches or he can undercut really badly by 2 inches. Only one of those 2 options leads to sinking the ball. It'd be cheating to say "let's add the possibility that he can undercut by 2 inches, but we won't ever overcut it by more than 1 inch"
On the other hand, maybe not. Maybe some people have a tendency to over vs. undercut. Like for you, it's not 33% of the time you split the pocket, 33% you over, and 33% you undercut. Maybe you or some other people will split the hole 33%, overcut just 17%, and undercut 50% (ranging from a .5 inch undercut to the occasional really bad 2 inch undercut).
For a shooter like that, I guess aiming to overcut a bit is safe because some issue with mechanics or visualization makes then undercut a lot anyway.
Caromsoft: I hate to say it but I think you might have the spirit of George Fels' quote wrong >_< ...Or maybe I misunderstood what you're saying. It sounds like you're saying that on those rail cuts, it's better to favor the outer facing of the pocket, basically you like to aim for the area in patrick's picture that is between the yellow line on the left and the center red line.
But I think the whole point of that quote is to explain to people that the physical opening that you can see out of the corner of your eyes is not the 'whole' pocket, the true 'whole pocket' includes getting some help from the pocket facing. Therefore don't limit your aiming point to strictly between the nipples, aim between whatever two points will allow you to take advantage of that facing to help the ball go in.
There are 2 ways to take advantage of that facing:
- Hit the facing directly
- Slop the ball in off the long rail and then into the same facing
Therefore I think what george would tell you is not to aim for that left-hand facing in patrick's diagram, or even halfway between those 2 yellow lines. He'd tell you to aim at the point labelled 'center of effective pocket'.
In other words, you don't aim to hit a little to the left (towards the facing), your ideal aiming point is actually a little to the right of the facing.
But, going back to my earlier point, maybe people subconsciously 'want' to undercut this ball, so aiming to hit it a little thin will always work for them.
I can believe george's book brought your game up 2 balls, maybe not for this exact reason though.
