(1) I would have shown that I could rotate the bat-head rearward with THT without rotating the shoulders.

> Why would you have shown that you can rotate the bat back with THT without shoulder rotation? It doesn't work that way. The bat remains cocked or stays at a 90 degree relationship with the lead arm while the hips start. The elbow is lowering as the hips begin rotation, the bat doesn't arc backwards during this time. The bat doesn't arc until shoulder rotation.

The wrists do not remain cocked if THT is applied. I tried it every-way I could think of and the bat loops and the hinge angle is compromised.

Jack, now your starting to sound like the second engine. Claiming it's the forearms pulling and pushing. If it's just the forearms then there's no need to even mention THT. Simple movement of the arms would be your cause, or simple rotation causing the arms to move. Or simple the lowering of the elbow would cause the forearm to move.

I don't think the pathfinder can determine if there is an increase or decrease in speed. It just pivots around a narrow/sharp radius. Perhaps a truer test would be swing it the lead hand and see how much batspeed is attained. Then it would act more like a hinge/double pendulum action.

Whatever wrist or hand torque there is, it's reactive. Caused by the swing itself. Or are we back to saying the wrists or is it forearms these days create batspeed?
