primary lever length at impact

[HungryBear]

I would lay a little TGM on the physics:

Useing the pro model only. ( who knows what the amatures are doing?)

1. Nice RHYTHM.
2. Assuming- a flat left hand and bent right wrist with on plane forearm- the HANDS move with and seen as part of the club, not the arm.
3. See the geometric release of #2 (THE VELOCITY ACCUMULATOR), as the true velocity accumulator
4. See #3 (TRANSFER) by comparing the arm rotational velocity to the club rotational velocity and noting the overtaking effect of #3 accumulator


Just my observation
