The "POINT", I was trying to make here is that the area is very small. Of course when the object ball is very close to the pocket you have a greater area on the object-ball that can be hit and still pocket the ball.
What you should do is put two balls together, I recomend lighter colored balls, one, three or five, and look at the point in the light. Roll the balls around each other and see that the area never changes. It's still small. Exact measurement, I really don't know.
All I know is the farther away from the pocket the object ball is, the more precise you have to be on your shots. EXAMPLE: IF YOU START A SPACESHIP OUT TO GO TO THE MOON AND IT"S ONE MILLIONTH OF ONE DEGREE OFF COURSE, THEY MIGHT END UP ON JUPITOR.
When you miss the same shots the same way you might want to take this into consideration. The adjustment to make that particular shot is going to be a very small area.
As far as the balls compressing, I have a hard time believing this happens. The ball would be rolling like it had a flat tire. Believe what you want to believe. That's just my theory.
