primary lever length at impact

[whip]

1) Can someone PM me innercity's address?
2) Whip - The section you quoted regarding Angular speed - that's RPM's - not clubhead speed. So Homer's contention is that the RPM's of the lever assembly stays constant upon release for the swinger and slowed slightly for the hitter based on measurements he made from photos in The Search for the Perfect Swing however realize the clubhead is picking up significant speed during release - due to lever extension etc. No book but I think the Release Section is the period of clubhead acceleration. Anyway a common mis-read that continues to confuse.

Correct he says that the centrifugal acceleration reaches maximum speed shortly after release and tries to remain constant, this is separate from clubhead speed which per the endless belt picks up speed significantly as the lever is extended going around the pulley.
