Calculation used to determine the relative amounts of energy required by the Golfing Machine to reach various velocities – not modeling around impact.
Other matters you allude to such as seemingly slow swingers out hitting those moving faster are cases of efficient transfer of power producing late clubhead speed. This is a matter of technique.

GMcG,
fair enough on the first point and totally agree on the second...however, i think the problem is that so much focus is often put on the parameter of clubhead velocity that it becomes the ultimate goal and obscures the more important technique of "efficient transfer of power" which i call "maximizing acceleration" at impact...well at least that's what happened to me, i think ...luckily, that is slowly but surely being corrected!
