I'm saying the equation that LP=A isn't correct. LP=MA is a much better equation. Essentially the greater the force the greater the lag pressure. Let's say you go out in front of your house in the street and accelerate (push) a feather 1mph, then to 2mph and then to 5 mph - not much lag pressure. Now, accelerate a car in neutral by pushing on the fender 1mph, 2mph, 5 mph - probably alot of lag pressure there. Acceleration was the same - the difference was the mass you were accelerating.

One example of that concept in a different perspective somewhere in the book 10-19? (don't have a book anymore), he comments for short shots with little to no hand motion - to add mass via extensor action for better lag pressure.

Therefore, if you had constant handspeed but were increasing angular mass via arm and/or lever assembly extension - you could still have lag pressure. Finally and in addition to that thought - we are talking about acceleration of the clubshaft at the grip end, where the hands attach. We're not talking about ONLY the acceleration of the hands through space, that has the ability to create lag pressure. Some of the wrist motions/muscles can add force and therefore lag pressure on top of whatever hand acceleration one might have or not have.
