Do you therefore believe that in a hitter's drive loading action, that the only factor is clubhead speed at impact and that push-pressure behind the clubshaft has no additive effect?

I presume that the clubhead must have a finite amount of weight so that the clubface doesn't deform at impact. Presuming that the clubface is sufficiently rigid, you are presumably stating that additional clubhead weight and/or additional push-pressure thrust exerted by the golfer has no effect on ball flight distance (other than its effect on clubhead speed at impact). Is that correct?

What about the possibility of clubhead acceleration through impact due to drive loading in a hitter's action. In your mathematical model, you are presuming that clubhead speed remains constant for the entire duration of ball-clubface contact in both situations. However, wouldn't increased drive loading (thrust force = push-force) allow the clubhead to continue to accelerate while it remains in contact with the ball for a duration of 1/4000 second? A hitter is not simply applying increased mass behind his drive loading action - he is also thrusting and accelerating the club through the impact zone.

Jeff, There is nothing the golfer can do during impact that can effect the outcome of the shot. More Here

Thanks for adding more commentary.

I need to think about this issue some more, although you seem to be correct.

Did you make a typo error at the end of your collisions paper?

You wrote -: "Prevent the club from drastically accelerating."

Don't you mean "decelerating"?

Jeff.... Yes... I fixed it now. I need to spell check and edit better. Also I like your approach ... simple documents with out fancy backgrounds etc. In time I'm going to put a bunch of docs on that web site and fix the index.htm page.

I look forward to your papers. I trust your maths more than Mandrin's. What is your url address for your index page?

After a hiatus I'm beginning to focus on golf again and hope to get things better organized soon.
