G2,
How about a summary of Matthew's new drawing- in regards to all components in the drawing, particularly Jen's Plane, the formula, and a real golfer?
However, I've been busy but I'm starting to get it- just going to take a little longer- Specifically Jen's plane role and definition would be helpful.
Mike;
I'll try to do a better job with this later, but I wanted to comment on the "real golfer" aspect. My opinion, and sort of along the line that bagger posted earlier, is that I'm not sure, nor I think is Matthew, of the future long term uses of this new information. I can see difficulties in it's initial application to the real golfer, in that the nuances of getting accurate measurements coupled with differeing golfer anatomy will make this difficult to apply. In swing analysis, the camera setup will have to be precisely oriented so that the computations won't suffer from differing camera angle perspectives. Also, the difference between traditional wristcock measurements from a front on photo (shaft angle to left forearm), and that calculated by this will be small since the only real difference is the fact that the #3acc plane and the sweetspot plane are only slightly different. At the top, the SSP, the #3acc plane both are the same. As you move down, the #3acc plane drops slightly below the SSP. If it didn't, the ball would be hit by the hozel. This effect causes the traditional method of determing wristcock, or lag to be slightly incorrect since the points of measurement are not on precisely the same plane. This new calculation allows you to evaluate the difference. More later...
