So much has been talking about the right

"Centrifugal Force -- not Right Arm Muscular Thrust -- does all the work in Swinging. In the Start Down and Downstroke, the Right Shoulder Turn Thrust 'cranks the Gyroscope' by 'blasting the Left Arm off the chest.'"

So much has been talking about the right shoulder turn thrust, in fact does the right shoulder actively driving the thrust? Or the #4 pp of the left chest shoulder when after the initial hip slide, then pulling through #4?
