Interesting stuff MJ .

Is this also true in terms of club head speed in general as opposed just to the clubhead speed derived from #2? If so I didn't know that! What about max radius vs less than ? The swinger not being subject to the slowing effect etc ? Although I never did wrap my head around that one.

Homer I believe stated that the club head slowed post low point but slowing prior to impact would be new I think. Or do you mean a slowing in the rate of acceleration as opposed to a general slowing down?

That's an interesting question - I was talking about #2 only, and I believe that's what Cochran & Stobbs and/or Jorgensen was talking about. My hunch is that #4(pivot power) and roll power(fastest move in golf) can overcome the slowing, which would explain HK's statement. I would think Swing Vision technology could answer that question very easily.
