The window of timing between cock and launch is not a "window"; it is non-existent, except for purposes of theory and discussion. There is no independent movement of the hands in this phase that is not associated with upper torso/shoulder rotation IMO. And for people to state that a batter "sets his swing radius" and determines the arc of the swing between toe touch and launch based on the location of the pitch (inside or outside) in this phase is beyond belief to me - NO WAY. Maybe the hitter pre-determines his swing arc/radius before the pitch is thrown and just executes it; I still doubt it very seriously. Now, tht maybe is something that "increases the swing arc" in an attempt to create early bat speed - o.k., but varying arcs based on pitch location in a "window of time" that I find hard to believe even exists is stretching it a little bit and overemphasizing the importance and significance of (tht) a movement that is questionable in and of itself. Rotational better than linear, no question; but then to take it to an extreme seems silly. <<< – (rogerh)

What is the bat doing -- bat head going back towards the catcher, setting up the swing radius, creating early bat speed? What is the purpose or why is this sequence so meaningful?

IMO, all the frame by frame video I watch, I do not see the bat head turn as early as you believe, but I would love to hear you clarify this so my EYES can be open. Thanks. <<< -- (rogerh)

The frames that would have shown the bat speed Barry generates during pre-launch torque have been left out. This sequence makes it appear that he comes to a static bat position in frame #3 (at least the third frame they showed). – If he actually did have a static bat at that point, he would be just another hitter.

Tom-
from your previous post (somewhere below)
"A scant 4 frames max of "launch" to contact."
I have counted this too. And counting other players I find most MLB players to be 4 1/2 to 5 1/2 frames from launch to contact.
Most kids are 5 or more.
Bonds is a marvel of efficiency and that added 1/30 sec is huge in terms of reading the pitch, deciding later than his peers, still generating HR batspeed by contact.
I am using that metric - frames from front heel down to contact as the measure of swing efficiency / swing quickness. Bonds is the best I've seen.
