Angular Speed - RPM - Rhythm

The Left Wrist and Clubhead should travel at the same Angular Speed.

2-P.....The true Angular Speed (RPM) of the Clubhead is identical to that of the Hands due to the mandatory Flat Left Wrist. See 2-N-1 and sketch 2-K#5. So as the Clubhead moves from minimum to maximum radius, its Surface Speed (6-N-0) in miles per hour (MPH) increases geometrically.

6-N-0.....The earlier in the Downstroke the Release occurs, the larger, longer and slower the Release Arc will be for both Clubhead and Hands. Other things being equal, this will require higher Hand Speed to produce yardages equivalent to that of the short quick arc of Maximum Delay. This involves Angular Speed which is measured by the number of degrees of an Arc through which the motion moves per second. From Release to Impact is just so many degrees of travel – at the Left Shoulder and/or at the Left Wrist. Doubling the travel time (for instance) halves the travel rate. Also see 2-P and 7-23.

One of my favorites,

7-23...The sharpness of the arcs at either end of “Line” Paths determines how much of that “Line” can remain and how much the change from Linear Speed (Downstroke) to Angular Speed (Release) will increase Clubhead Speed without changing Hand Speed – the “Endless Belt Effect” of #3 Accumulator per 2-K#6 and 6-B-3-B.
