cushion nose height vs ball midpoint

I`ve read that the correct contact point of the cushion should be 1 7/16"above the bed.The midpoint of a 2 1/4"ball is 1 1/8".Why wouldn`t the optimal contact point be the exact center of the ball,rather than 5/16 above center?Obviously,the 1 7/16 nose height is correct,but the physics of it escape me. RKC? Thanks.

The 1 7/16th will keep you from losing any teeth when the balls hit the rails.
Think about this...the ball going into the cushion with speed....impact the cushion and return....if the cushion didn't help control the ball in a downward direction....and keep in on the table....the ball would fly up off the table and hurt someone.

The rolling action of a ball striking the rail will cause it to climb the cushion and take off if not for the extra height of the nose. It will still climb and fly off of a 1 7/16 nose if you bounce the cue ball a little by jacking up with top spin.
