Personally:

-I think you can be Hands To Pivot and Shift Planes.

-I think Plane Shifts influence the Hand Path, obviously. 10-23-A is Single Shift , 10-23- B,C and D are Double Shift.

-But Hand Path does not determine the Release Point. You'll notice that 10-24 illustrates all five Release (s) using the 10-23-C Hand Path (Double Shift).

-I believe Plane Shifting is hazardous , for sure, but so is crossing the street. You need to rank your hazards. Hogan was a Double Shifter and hit out of his own divots. Plane Shifting should be ranked way below Plane Line compliance in a hierarchy of Geometrical needs.

10-23-C is a Straight Line Delivery Path and does not shift during the Downstroke. It is not a Double shift. Please re-examine.

Hand Path does not determine Release Point but Elbow Path Does. And, the Elbow Path for Plane Shifters is Always the same.

I'm amused when I listen to Golfers say that during the fleeting second of the Downstroke, that one can consciously aim the #3 PP first downward and then outward toward the Plane Line and additionally, if by magic, the Clubshaft and Clubhead move to the new Plane Angle by themselves, thus acting on their own. Do all Plane Shifters use 2 Aiming Points? One for the Downstroke and another for Release through Impact and Follow-through?

Here's an interesting Book Quote that most readers miss. Page 208.

The Flip Release procedure always uses the Shoulder Turn “Takeaway” (10-6-B) which produces a curved Plane Shift by both the Hands and Clubhead. This is part of its Body related (not Ball related) execution as “Pivot Controlled Hands” referred to in 5-0. The Pivot may be educated to produce geometric Hand and Club alignments and relationships with some degree of precision which definitely improve control. Expanding this infiltration could serve as your “Relative Translation procedure (3-B) to true “Hand Controlled Pivot” procedure. But – except as a temporary Band Aid, any mandatory Component position or location can only be disruptive and carries a prohibitive price tag. See 1-K.
