One of the problems is, like golf, you have to watch your target, first, to insure your ball rolls over it. (Golf; you keep your eye on the ball until after the club hits the ball, or at least you're supposed to do that.) Then you have to pick your eyes up and watch the ball enter the pocket and fall off into the pit.
It's just something you have to get used to doing via experience Try it during practice sessions first.
Heck, I know people who have no idea what their breakpoint point is or if their ball even gets near it. I guess part of the blame lies with the house shot and many (not all) people's tendency to start left and throw right. They can hardly stay within 10 boards of their target, no less actually watching where their ball goes.
