Mr Kelley defines "Pace" as The surface speed of the orbiting Clubhead - as differentiated from Rhythm.
He urges us (6-P-0) to never make a shot BUT to make a ([non-automatic] release) "Motion".
Quote:
"Your Motionmust include its Pace, that is hand speed (RPM) strong, consistent and RHYTHMIC".
So, a non-automatic release procedure is invoked in order to produce "Pace" - a steady and constant hand speed, augmented by Trigger Delay to produce the desired effect.
Therefore, there is no connection between "Pace" and "Rhythm" unless a conscious decision is made to keep both lever assemblies at the same RPM - in which event Pace is sacrificed in the interest of maintaining Rhythm.
