I thought the below graphics would make for good disscussion.

...the result all TGMers know—the left shoulder moving UP and the clubhead moving DOWN, WITH a FORWARD LEANing shaft—exists.

Thanks for these graphics, Brian. Very instructive!

Five points:

1. Per 2-N-1, the orbit of the clubhead is an On Plane Resultant Force -- the product of two divergent forces (one Outward and one Downward).

2. The Axis Tilt (produced by the Hip Slide), along with the Uncocking Left Wrist and straightening Right Arm, produces the Downward Force vector.

3. The Downstroke Right Shoulder Turn (not Left Shoulder Turn) creates the Outward Force vector and also, by virtue of the Axis Tilt, creates the On Plane Resultant Force vector.

4. The Left Shoulder Impact Location (7-8 ) is determined by the Left Shoulder-to-Ball Radius as established in Impact Fix per the Address Routine of 2-J-1. To the extent it lowers 'down and around' in the Adjusted Address and Backstroke, so it must return 'Up and around' to its Impact Location. The amount of forward Clubshaft Lean (2-J-2) is likewise determined in Fix.

5. Without a Stationary Head to stabilize the Pivot and Educated Hands to maintain the On Plane alignments, the precision required of these actions is at risk.
