Isn't the case where body rotation starts the gyroscope, then it's all cetrifugal force. Any active addition of pivot would disrupt the action of cetrifugal force. Body responds to centrifugal force. Cetrifugal force creates clubhead change (sustains clubhead lag). All the swinger has to do is get things started.
This is pretty much what i was trying to say - the pivot drives the powerpackage into orbit around a stationary post/something/head/base of neck and release 4, then 2 then 3... the pivot doesn't stop moving but it slows during the accumulator releases and moves just enough to enable sutained lag pressure... but in a swinger the pivot is not driving the lag pressure.... at least that is the way i have interpreted it.
Thanks for your comments guys. Helpful discussion for me!
