Arnie . . .

. . . was his shoulder move in Startdown Motion or Work?

Thanks for this, O.B.

In the Start Down, the Right Shoulder Acceleration is actuated by the Hip Turn. This Hip Turn -- with its Action -- is more than mere Motion. In fact, it does the work that throws the Right Shoulder (and with it, the entire Power Package) into Release.

Motion permits but causes nothing.

Work actuates and causes everything.

Arnie definitely pulled the Club from the Top.

Then, from Release, he drove it through Impact and Follow-Through.
