I've glossed over this 100 times. Does this mean that "Mass" increases during the Release Interval as long as Lag Pressure is constant?

TIMING
6-F-0 GENERAL The term “Timing” as used in Golf means to bring about Impact during the moment of the Clubhead’s maximum Force. With the Rope Handle technique (2-K), this “moment” starts at Release and its “Overtaking Rate” is a very even speed, right up to Impact. Except for Clubhead Lag Pressure it is almost exclusively the generation and utilization of Centrifugal Force. With the Axe Handle technique (2-K), top speed is also established at Release but its “Overtaking Rate” tends to decelerate, making Trigger Delay and Timing much more critical. It is almost exclusively Muscular Force, totally annulling and stifling any intrusion by Centrifugal Force. See “Swingers and Hitters.” So, the Clubhead is not picking up speed during the Overtaking (Release) Interval, either when Hitting or Swinging (6-C-2-B, 7-19). And carefully study 2-N and 2-P.
Hmm? I think that Homer is saying that although a dramatic speed increase occurs at the moment of Release, it then remains constant. And, although the #3 PP remains constant, which is Acceleration, the pressure causes an increase in Mass.
"So, the Clubhead is not picking up speed during the Overtaking (Release) Interval, either when Hitting or Swinging (6-C-2-B, 7-19). And carefully study 2-N and 2-P."
That's just Homer Kelley in his own world - not realizing how or when to be clear in his writings. Or put another way - if you read the entire 1st paragraph in 6-F-0 - he's assuming that you know that he is talking about "Overtaking Rate" - Hand speed - RPM's not clubhead speed. When he uses the term "Speed" in that sentence - he's referring to RPM speed - he'd be the first to acknowledge that the clubhead is picking up tremendous surface speed during the release.
He actually measured the different shaft locations during release for two different swings in the book "Search for the Perfect Swing" - one he determined was a hitter and the other a swinger. From that and other assumptions - he determined that the hitter's RPM slowed down during release (that is the distance between subsequent shaft locations during release became slightly smaller with the hitter).
Expecially important here - if you use his cross reference to 2-P, you need to have the 7th edition as he much more clearly differentiates the #2 and #3 accumulators and clubhead speed versus RPM speed in the 7th edition re-write in 2-P. The cross reference to 2-P in the 6th edition from 6-F-0 just creates additional confusion.

Ya but.........if lever extension is associated with a slowing of clubhead speed then Lag Pressure leaks away too.
Bear your a man of science, if this is true, that #2 angle extension leads to a loss of clubhead speed then why did Homer label #2 as Velocity power?
Thanks
Yes. When the force that moves anything is removed it will start to slow down. It is easy for #2 to add but when it stops adding no more acceleration from #2.
