Hand Speed vs Bat Speed thru the swing

[fanboi22]

I call it an "rotational point", the hands/forearms, along with the back hip being an rotational point.

So the two of them set up a deep rotational point.

Thanks. How long does it stay rotational? Until contact? After contact? Or is there a linear motion at some point after the initial rotation to get the barrel to the ball with whip? Thanks again appreciate the input.

It's not really linear "after" initial rotation, it's linear before rotation.

Not that it matters........

It's (hands path) 'rotational' then it's 'linear'.......

Then its linear unless its an inside FB. Then it might just continue to rotate and get linear after contact.

Also the 90 degree to the top hand forearm is a approximation. It is adjustable. Also the angle become slightly more acute due to loose grip at launch and create lag/whip. Its not a lot but it's there. Can a hitter have to loose grip? yep! Too tight? absolutely. Tinkering with different grips and grip pressures with a sensor can help increase bat speed.

I was wondering when the hand path rotational/linear would come up.

So can the swing be both, TTB and bat lag?

I guess it depends how much lag you want. Personally I see lag as a pass through position. Not something that should be maintained. Attempting to maintain lag reduces barrel speed.

Agree with the grip quotes. I have variables that I allow with the grip...measuring pressures would be useful. What gadget do you use to do that?

Depends on what your asking, are you asking about hand path or the body? Are you asking about body rotation?

I just call it a rotational point. That doesn't mean it's a unmovable point.

I think I understand your post better.

No it's not an immovable rotational point. For example the back hip rotation point moves to the front hip during the swing. So no, it's not an immovable point.
