I interpret nmgolfer's post as indicating that golfer C would not generate a significantly greater ball velocity than golfer A, and that golfer C's clubhead will not slow significantly less than golfer A's clubhead as a result of ball collision.

What about golfer B compared to golfer A? What does HK mean when he envisages a swing radius extending from the feet to the clubhead, and what effect does this "mental construct" have on ball velocity and clubhead slowing as a result of ball collision?

Jeff.

Where are you getting "mental construct"? That's your words not Homer's . . .. He's talking about pivot lag . . . not some kinda concept deal. You either got components lagging from the feet . . . or somewhere further up the pivot chain . . . . that's what makes the difference . . . . lag in the pivot works . . . lag in the brain or lag in the construct . . . not sure about those.
