From The Top when Swinging, the Instant Acceleration Hip Action Cranks the Gyroscope, i.e., it Loads the Lag in the Power Package.
In the other forums, you stated that the right shoulder thrust cranked the gyroscope, a downswing starting motion which I never understood, nor saw any player execute. Now IAHA makes a lot more sense. Consistent with a left side pull and an uninterrupted pivot train.
