[Yoda]

I had a particular sectioned which I was using for my own swing. I suddenly
realized that it was in fact the passage I had remember HK remarking about
the radius in. I can't believe it didn't come up earlier.

The spine, between the shoulders, is the center of the Shoulder Turn only,
not of the Left Arm, except by specific extension of the Swing Radius.

Ringer,

This has "come up earlier." Go back four pages (to
page 6) and my post on 10/14 at 18:56:

"The Golfer's Flail -- the Left Arm and Club -- is the Primary Lever
Assembly (6-A-2) that ultimately applies Force to the Ball. It is attached to
the Body at the Left Shoulder. Pivot Lag -- Body Power for Swingers and
Launching Pad for Hitters -- is the 'gear train' that uses multiple Centers
(Shoulders, Hips and Knees) to extend the Swing Radius of the Flail
to any point from the Shoulder Turn to the Feet (6-C-0). However, this
'gear train extension' is not the Flail itself. It is the mechanism by which
the Flail is accelerated.
