Thanks Yoda, 12 piece and others for taking part in this discussion. I think the mess I started is more or less cleared up now.
Lets talk about the second point I made that started this thread:
7-1, last sentence:
"The prestressed (bent) Clubshaft (10-19-A) and maximum Swing Radius (10-19-C) are resistances to Impact Decelerations that each must establish before – not during – Impact (2-M-1)."
What bugs me are the terms in parenthesis. Why is the prestressed Clubshaft associated only with Drive Loading (10-19-A), and max Swing Radius associated only to Drag Loading (10-19-C). I thought Swingers should also go into Impact with a prestressed Clubshaft, no? Likewise, Hitters should have max Swing Radius too, no?
