What starts it (club) back?
What keeps it going to the Top or End?
Homer and Lynn talk about a reverse pressure point- #3, aka extensor action.
Extensor action continues to bring the hands to the top as the right elbow bends- the left arm straightens and the left shoulder reacts to the right shoulder's turn.

What starts it DOWN?
What keeps it going through IMPACT on to the Finish?
A hip bump. I can't tell you how important this is. It is a small, slight move that sets the pivot and the power package for delivery. 10-14-B.
Aiming point, full arm extension finishes it.
