PERFECT! Thus . . . SUSTAIN the the LAG not INCREASE the LAG. Now what do you say about "lag is a consequence of Newton's 1st law: Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it." . . . for a Hitter. If we have applied thrust via the turning of our body (phat donkey and all) . . . AND THEN one's Right Tricepts takes over have we annulled "the conservation of angular momentum" as a result? Would you say the Physics are different as a result of the Right Arm supplying the "thrust" or "acceleration" or whatever?

How'd you know my hiney had dimples? Beware "Killing me." Mikey is LURKING. He forgets his medication sometimes.

Applied force is applied force. As long as the lag pressure is felt at PP3 throughout the down (out and forward) stroke, then the Hitter is still applying force. However, if one plotted lag pressure vs. time during the down stroke, then one might see variation as different components dominate as the force appliers.

Actually, some of the more advanced swing analysis places measure and plot clubhead acceleration during the golf stroke. It is an eye opening and humble experience. The Titleist Performance Center folks probably do it. Don't forget, acceleration makes the world go round.
