But the top hand doesn't fully uncock/release (whatever) until the lag position is attained, which is roughly the last 3 to 4 frames in the video clip.

I certainly do not believe there should be any pause in angular acceleration at that point. An over-head view of a great hitters swing show the bat-head accelerating right through what we refer to as the lag position.
> You state, “But the top hand doesn't fully uncock/release (whatever) until the lag position is attained.” – We may interpret “uncock/release” differently. With my definition, the top wrist is most “cocked” at the lag position and “uncocks” approaching contact. I cannot see how properly applying THT would alter that.

Hi Jack,

The problem I see with THT is wrist may uncock to soon. I'm still looking at this and how it affects the swing. I have game footage and HR derby swings with shots from the rear and side view of the same swings.

Right now it would appear that the top hand 'follows' the bottom hand. I'm looking at how much the bat is accelerated length wise (down the barrel) in the swing. To attain the lag position the top hand cannot uncock to early.

I'll get back to you on what I see happening.
