The Hands resisting the change of direction at the Top . . . is this "leaving the hands at the Top?" And the Pivot thus supplies the initial Load to #1, #3 and the Right Elbow?

1. No, "leaving the hands at the Top" refers to the Lower Body leading the Start Down from the Top. "Resisting the change of direction" refers to the Hands deliberately stopping their travel during the last stage of the Backstroke, thus causing the momentum of the Club to load the Pressure Points.

2. Unless the Pivot itself -- specifically the Right Shoulder Turn Thrust -- is actively used to take up the Clubhead's Angular Inertia (the Clubhead Lag / 10-19-A), it supplies only leading motion and thus cannot be considered a Power Source.
