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?

It is the difference between longitudinal and radial forces (at the limits of each).

If something is fully longitudinally stressed, it can not be bent. Likewise, if something is radially stressed, it can not be straight because 'any' amount of radial force creates a 'bend', technically speaking.

Does this mean then that a 'pure' swing, pure longitudinal acceleration, would mean no PP#3 feel/lag pressure at follow through? Where a hitter would always be 'bending the string', and a swinger would 'snap it straight, at both arms straight' and have no radial force (lag pressure) at all at that point? The point at which you would feel your "arms coming out of their sockets" to quote Ben (or something along those lines). Miller talks about this feel too.
