If the pivot tries to add - above and beyond, alignments and rhythm suffer.

If the pivot supplies the power and one cannot add with the hands what good is extensor action??
The video of Homer swinging quote, "coming down on the ball as if to drive it into the ground". No mention of pivot only the hands driving the ball into the ground. The pivot follows the lead of the hands going down and out.

You misunderstand extensor action- it moves nothing. It does not move the left arm just tugs it, stretches it like a stubborn tight bungee cord that needs constant attention to remain pulled.
That is not adding. Adding is removing rhythm by forcing more hand into the stroke near impact.
Ben says no “adding.” Yoda says “no try just do.”

Read in the glossary Homers definition of Pivot, “.....holding the clubshaft “On Plane” by positioning and adjusting the Lever Assembly, through #3 Accumulator, as directed by the right forearm.” (And my guess the Flying Wedge Assembly too)

A trained pivot is the number one zone and the point Homer said to begin. To me the pivot is the hips- the hip action and its motion. The hips must clear. As Ted Fort says, hips cannot be roadblocks, they must be highways. And that comes form a trained pivot.
There is nothing wrong with the pivot moving the hands or the pivot responding to the arm swing and hands. They’re both move the same way because both must be hand trained and both MUST produce the same Pace and Rhythm into impact. How you want to perceive it is just semantics and your “seems to be.”
