uhmm..... I like to put it this way.. what i know.. may be wrong but .. I'll bite.
Club head speed is created by

1) the maximum accumulator you can create ( Higher distance for acceleration) + the Maximum trigger delay you can make which translate to higher Rate of Release = SPEED . a combination of these = SPEED, Thus hand speed is = Strength to hold on + how fast your muscle can follow up with the release, thus grip, forearm strength and speed are very important. This part can be Very very fast and violent irregardless of tempo.

2) Rhythm is the RPM that need to be maintain ( body and arm at the pulley part of endless belt)and Tempo is speed . but a large pulley speed Travel Fast. Does it matter? yes but not as huge as no.1 i would say less important. The larger the PULLEY.. The LESS efficient as Homer explains... Larger Pulley require Higher Hand speed to maintain rhythm( cause travel further). he say Require ... NEED.. and thus club head speed is inter-related with Point 1. Which mean you can use a BIG pulley and HIGH hand speed as in big pulley and the MPH not really fast.

so.. Hand speed .. 2 kinds...

1 Now strong and fast the educated hands and brain can hold on and follow up (maintain lag pressure) to a violent faster rate of release..

2 How fast the hand have to travel in a huge pulley to maintain RPM, which have a more "passive role" in a PIVOT transport or accumulator 4 case because of PIVOT transport.

The smaller the pulley, the slower the hands required to maintain rhythm, thus more efficient, the bigger the pulley the more acceleration can be created.Diminishing returns.....

But the way I think is,, the less effort to create higher output a person can create, the better and more efficient he is, thus relying on faster rate of release is more reproducible and less taxing on the body( fatigue) thus much better mechanics and powerful.

Thus... its my bias opinion.. a turned shoulder, 3/4 barrel swing , with a cupped left wrist at the end,with a Flip release and a long back swing can go the furthest with least effort.. not neccessary the most repeatable..

I'm going crazy...
