Biomechanic - you wrote-: "when we measured tour players most guys swing and hit at the bottom. This is measured science, not using video which won't indicate."

How did you determine (in a measured scientific manner) that tour players (who swing) hit at the bottom? What is your definition of "bottom"? How did you scientifically determine they that were using active right triceps thrust action to release PA#1 at the "bottom"?
