Yoda, thank you for your response

I still see the c7 as the pivot center but rather then turning around the whole spine like a bottle rocket I see the spine as a pendulum with the weight being at the base, just about 2 inches deep of the belly button. and the c7 as being the pivot point This will keep the head much more still so to speak, and in some swings may actually have it move a little forward in the backswing,. In the compound pivot the first thing to happen in the swing is the weight shift to the right/rear, which keeps the c7 in the same spot but moves the base/bottom of the spine. IN the bottle rocket pivot it turns the backswing into a pivot where it becomes a door on three hinges so to speak, then in the downswing you have to go from three hinges to the c7 pivot center.. In the compound, which looks very similar to the pivot you are talking about, the swing center and ONLY pivot point is established on the back swing and maintained on the downswing. IN the barn door/bottle rocket you have to change during swing which seems like more work. I understand the debate you mention and I no longer like to argue about the golfswing but rather discuss, too many other things in life to raise my blood pressure.

so why do I ask these questions and bring them here?
because since the pivot proffered here is close or the same to the pivot I want to try, the compound, I want to figure out how I can shift my weight back in the back swing as my first move, lagging club head takeaway, without reverse pivoting or swaying

C7 is the medical name for a section of the verterbea near the base of the neck. Austin likes to use that as a post to swing the hips from- the compound pivot in his words.

TGM does not think about positions of body parts but geometric lines and force applied on and along these lines.

The SPINE is NOT a bottle rocket- not for Austin or anyone. The spine re-adjusts itself throughout the stroke- the spine is not straight-(see Skywalker posts on the spine). This is why the head can remain stationary under a remarkable and mis-understood spine. The barn door turn is the worst image anyone can have for a pivot. Austin once said that turning the hips moves the head off the ball- that is because he saw the other option as the barn door. That is a Ballard move aka Sway. The spine re-adjusts because the shoulders are independent from the hips.

TGM discribes several options for hip motioin and hip actions.

Tripod is not a set up for hip action but a part of the stroke that prevents sway and keeps the geometry of the circle intact.
