please explain the data and show me what it concludes or how it proves your point. the endless belt is a great way to understand the release and I know greg smith and I have discussed it many times during practice. wheres the data, what supports your point? what point do you have?

Strive for a continuous, smooth, constant hand speed throughout for all shots, from tee to green and I promise, you will be a better golfer. this is practically half the mechanics for me along with extensor, constant hand speed and extensor ARE BIG DEALS

Look at the graphs in the study! I've already discussed them above. The endless belt doesn't have an uncocking club attached to it, only a duck!

I suspect that you say this because you are a sweep releaser and that's how it feels to you. You probably have a circle hand path, which would mean you don't really have a pulley. In that case you have to feel a "smooth, constant" hand speed in order to avoid so much #2 throwaway that your hands can't get to the ball before the clubhead.

whip, you should not be aware of hand speed at all, since the necessary hand speed in a Swing is provided automatically by the pivot actuation of #4 and then #2, ideally properly sequenced and lagged. Look again at the pro graph in the Cheetham study. You want peak hip speed to precede peak thorax speed to precede peak left arm speed, which decelerates rapidly before impact. To get this, you drive the right shoulder while keeping #4 fully loaded, so it can "blast off".
