Come on guys!

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.

> I apologize for misreading my notes.The angelfire clip is still working.I estimate end of bat cock/beginning of uncocking after frame #11(hip cock).Hip can be seen uncocking in frame #16,but torso doesn't launch until after frame #17(torso has turned in frame #18),so that's > 5 frames of bat turning before the torso kicks in at 30 frames/sec.Contact estimated at frame # 21.
