I still remain unconvinced by any argument that supports the idea of a pivot center and/or a pivot axis, but I will consciously remain open to any "new" thoughts regarding the issue.
Jeff.
Hey Jeff
So given your statement in your last post that you now do "imagine that the axis of rotation is a diagonal line drawn between the left foot and the swing center" can we take from that you now acknowledge the existence of the axis of rotation and the pivot center (or swing center)?
Have you found two new concepts to adopt? Can we go to the "tote board". One TGM one VJT (or is axis of rotation somewhere in the yellow booK? I dunno)
In regard to whether the pivot center is directly between the feet. I like Henny's note that if it isnt it requires compensations and Bucket's that if it is back of center it is draw or pull biased. Good observations there. The "uncompensated" swing will have the pivot center in the middle of the feet.
As for your note about the diagram on page 37 of Vj's book, illustration 11, I understand your confusion. I wonder if anyone has noted this before. Interesting.
I think it is a typo. That the line drawn from Hogan's left shoulder to low point should be labeled as the Impact Circle Radius. Page 49 ; "The true radius of Hogan's impact circle is a line from his left shoulder (at impact) to a point in front of the his ball (the low point of his swing)". Brackets by the author.
