Id say No, not past the point where the club is not accelerating anyways. But the attempt or the intention to sustain it as long as you can is a good one. A very good one assuming you want to hit the ball with an accelerating clubhead as opposed to a decelerating one.
There's a lot of different definitions of lag out there but I'd like to confine this conversation to Homer's Lag, Lag Pressure. Lag PRESSURE as sensed in the Hands, the #3 pp (rotated or not).
Here's my line of thinking please tell me if you think Ive got Homer wrong. It aint hard to do.
Lag Pressure is a product of Acceleration. The rate of acceleration to be precise. To maintain a constant amount of Lag Pressure you need to maintain a constant rate of acceleration. (which is one difficult task) Any slowing in the rate , though you may still be accelerating will see a corresponding drop off in the amount of Lag Pressure in terms of psi. (Lag pressure as defined is not measurable in terms of degrees or inches).
O.K? Stick with me here. Homer in the Law Flail 2-K noted how when the (swingle) clubhead passes the (handle) hands that the clubhead is subject to what he termed "Angular Deceleration". To me implying that Lag Pressure is fully diminished by this point.
Further more I believe the Endless Belt analogy is a model to show the mechanical advantage of the small pulley wheel for a given hand speed only. I dont believe Homer was suggesting there was an advantage to having a constant hand speed!!! In fact a constant hand speed would to my mind suggest a lag pressure of zero. This may be contrary to some well intentioned A.I.s teachings.......no ill will intended. I just think they got Homer slightly wrong. Either they did or I did......
Any thoughts on this guys? Its time to get Homers definitions straight however painful it may be to the memory of some pioneers. There's some guys dressed up in lab coats , calling themselves "scientists" who are looking for some misinterpretations to rebut. Most of them are of their own making but lets clear up our own.
