Maximum Compression

[John Graham]

John,

In the precision Sketch 2-C-1 #3 (2-N-0 / Geometry of the Circle with Separation deliberately assumed at Low Point), the Swing Path (Arc of Approach), the Clubface and the Line of Compression each face directly down the Plane Line (in this case, also the Target Line). TGM contends that this configuration will produce maximum compression (no "glancing force") and a dead straight shot.

Under these exact conditions, does the D-Plane concept predict another result? If so, what? If not, then in this specific instance, how does D Plane theory "trump" Geometry of the Circle / Hinge Action theory? Or vice versa? In a non-adversarial world, could they be equally predictive?

Lynn,

Thanks for the question.

Are you teaching people to produce seperation at lowpoint as described in 2-C-1#3 to produce maximum compression (no "glancing force") and a dead straight shot?

I doubt it.

Clearly, you understand and respect D plane well enough to know that this is the only way you can phrase a question that matches the book in some way.

It's not really the geometry of the circle as I see it drawn on napkins, easels and pieces of paper is it?

This was my experience and I still have not been convinced.

Again, I am quite open to discussion.
