I think the yellow line is the imaginary mathematical Axis of Rotation. The spine is not the axis, it precesses around the axis on a tilted spiral. The front leg itself is not really the axis either although it's close, the ankle is the base of the axis as everything pivots centered around it.

If the rear leg was the axis of rotation, then it would be moving/wandering around during the throw which would kill rotational velocity.

I think the discrepancy here is that we are both right. There is an axis of rotation how I'm seeing it where the spine and the rear leg are on the axis first. That starts to fade away very close to the hit (most pro's release the front toe just before the hit) and the front leg starts to rotate. Then there is a new axis of rotation that does include the front leg and does not include the rear leg. In my coaching I find it most useful to

I remain confused.

TDG talks about a stationary axis in his OLD phase 1. That is roughly head through spine through back leg.

The photos of pros both in the coil position and at the hit looked tipped away from the target and roughly through spine and front leg - but on followthrough they are tipped toward target. As if the axis of rotation had moved in a cone shape (point at the bottom).

My question is about the hit point itself. At that time, is the axis essentially stationary, wherever it is pointing? So the majority of rotation occurs around a relatively fixed axis, that may have slowly precessed to get to that spot, and then continues to slowly precess to followthrough?

Also important to know there's a small change in runup line angles that you commonly see between hyzer vs anhyzer throws.

Umm. Not saying you're wrong. But I had a somewhat different interpretation. So......

Consider the shoulder plane. It wobbles a bit during the throw, as Tread Athletics graphics show, but near release it must be fairly stable.
I would think the axis of rotation at that instant is a line perpendicular to the shoulder plane, and possibly (probably?) passing through the center of mass.

I liked this bit of Paul demonstrating his rhythm and balance in the x-step from the recent video he did with Drew Gibson.

I saw that and thought it was cool too, and was funny that he said something about having no routine lately which I interpreted as when you get too, used to your routine and it becomes too subconscious it slowly evolves until you find yourself later on wondering why your routine seems often different and you have to work again and clearing it up.

Funny how he noticed that his swing to the right was missing right away I also posted this because I never really got the move paul does as it seems really wide to me with some east/west movement while I usually have more of a south/north swing thought in my x-step to get stretched out like Simon does. But this little demonstration made it much easier to get the rhythm Paul uses for his x-step and that little swing to the right coupled with the pump at the hip makes it much easier to go slow and controlled into the x-step. For me the more pronounced east/west movement also makes it easier to load my left hip as I can load it against the movement of my arm.
