Jack -

I would say you want more segmented/sequenced release of energy as opposed to turning evrything too much together. Turning too much together would be "Spinning" and "flying open" and "pulling off the ball".

The result of a well segmented swing can be measured by motionanalysis as the expected "speed gains" from each successive arc as with the arcs of your model and the data from Zig's motionanalysis.

I think the key sequence is:

1 - "prelaunch THT" which is the synched upper/lower body "running start" where handle is torqued to uncock bat as hands and shouldwers stay back and lead leg turns open (turn the bathead/turn the heel) as you "rotate into toe touch". Back elbow starts down, front elbow starts up mainly by internal rotation.

prior to this there has been the inward turn and the tilting of the front shoulder down with the negative move and the cocking of the hips and hands with the positive move, THEN

2 - "tht at launch" or drop and tilt as the result of superimposing the "GO" move on the coiling already underway.

The KEY here is that the shoulders TILT front shoulder up/resist (rather than turn/fly open) as the hips fire to create "frontside stretch" that "keeps the shoulders in there" and prevents flying open and pulling off the ball.
