I know what you are saying here, MJ, but your post may fog concepts for those without your advanced knowledge and ultimate refinement of the movement.
The Golfing Machine® System of precision alignments mandates Hand Controlled Pivot, not the other way around. That does not prevent the Pivot from Loading the Lag during Start Down and setting up the entire Centrifugal Downstroke Release Sequence (which I believe is the point you are trying to make). Indeed, this is exactly what should occur in the full Stroke.
However, at all times, the Hands monitor the On Plane Clubhead Lag and thereby control the Pivot and its Motion. In fact, Overacceleration and its inevitable Clubhead Throwaway always "disregards the Hands" (6-D-1).
