I am not talking about either of those centers per se, but about the
radius of the circle of a point from the pivot center, to PP1 - the line
in 3 demensional space. While the 'length' of that radius isn't constant
during the entire swing, its plane is (ideally, given zero plane shift).
[Bold by Yoda.]
I'm all for 'orignal thinking' and write this post in that spirit.
In a Zero Shift Stroke, the Hands and their On Plane Pressure Points (#1 and
#3) swing on the Turned Shoulder Plane. That Plane is by definition
Flatter than that of the 'Point between the Shoulders' Plane -- the Squared
Shoulder Plane you have described. [Or at least that I think you have
described.]
Also, I do not understand why this 'Spine to Pressure Point radius' concept
is relevant. Given the Primary Lever Assembly (Stroke Radius)and its #3
Accumulator and Rhythm, what does it contribute?
You are rapidly increasing your understanding of one of the Three Major
Concepts in The Golfing Machine -- the Inclined Plane. Once you
get this, you will have taken the next step toward becoming a truly fine
player. By his own admission, Ben Hogan didn't 'get it' until his
mid-thirties, and it was only then that he won the first of his many major
championsips.
You have illustrated the Plane of the Squared Right Shoulder at Address.
Brian's post referenced the Plane of the Turned Right Shoulder at the Top.
