I haven't seen Yoda in person, but his ball striking looks very very good to my eye. I will never look as good and the more I try to copy him the worse my ball striking gets.
I don't believe in forcing an early release of the peripheral parts of the golf stroke. Per HK you don'e want anything above to catch up with anything below before the ball has gone. Drive the feet, drive the hips, drive the shoulders, drive the arms. If the ball hasn't gone by then you can try do drive the club as well but it will not make a big difference IMO.
I've tried a lot of things lately. And quite a few others a few years ago. What it boils down to me is to maximize the pivot thrust. With differnt swings, as long as I get the geometry right, the swing speed basically remains the same. One of the things that differs is thrust through the ball. Another differentiator is the stability.
Forcing a release of the club will slow down your hands. Forcing a release of the arms will slow down your pivot. I think you should build things from ground up, and first do as much as you can with the pivot - then with the arms and then fire the club.
With a slight modification for hitters: You are allowed to do peripheral activities as long as they don't override the central movements.
Personally I'm convinced that the best way to create a powerful release of accumulator #2 is to use everything you've got to charge it during the down stroke. When CF takes over you can try to add a little extra. I don'd believe in hammering the hand and arms down the inclined plane as an active move because you have to slow down your pivot to do it. But I believe it may be a good teaching device to get rid of the steering mentality.
