A frame-by-frame analysis of their swings shows that their axis of rotation is not the front-hip. They rotate about the center of their body – the spine.

Jack,

I agree that rotation is not around the front hip, but I am not in agreement that rotation is around the spine.

In reading your post I believe you stated that the forward push is not turned into rotational energy.

Can there not be forward momentum with out weight shift until "go"? Can't the weight shift put the front foot down, so your weight will remain over your rear hip? So the axis of rotation is not really an axis but a joint the rear hip to be more specific.

I ask because IMO the body produces forward momentum without the weight shifting until you push off of the back leg. The back leg and hands sync together, similar to throwing. The weight shift is blocked by the front leg.

I may be rambling a bit, again hard to explain in written words.
