[Yoda]

You showed the total motion from these great players. But Yoda showed the basic motion. I didn't know that so much was going on at this first stage.

There is a misunderstanding here, and it is due solely to terminology.

This was a personal video shot several years ago for a specific purpose. Namely, to offer a solution to an injured player (Brian Watts). It was never intended to be posted here. It is here only because of Pluto!

I made no reference to TGM. In fact, the movements shown have their origin in Bob MacDonald (Golf / 1927), not TGM. Within the context of my video message to my player, I stand by my statement in the video that the combined pivot and arm swing constitute the 'basic motion' of the stroke -- its "fundamental nature" -- knowing full well that a strict TGM definition would label the degree of motion as Second Stage (Acquired) or even Third Stage (Total).

Your confusion does make an important point:

What we call things matters.

If we can't agree on what our words mean, what chance do we have communicate?
