This is an excellent point JAck. Problem with measuring time of swing is that it is hard to define launch with a low enough error.

As for length of path, Jack describes what I consider to tbe the optimum belly-up/quick type swing and he has measured how far the hands go as a way of demonstrating how short this is.

JAck,given a good high level hitter, have you measured the handpath in in vs out swings and compared them ?

The outsdie swing has a longer swing radius, but the high load sucks the momentum out of the torso faster so the torso does not turn much.

On the insdie,the BHT/pull has a very short/low load swing radius, but the torso turns much more, ?then dcelerates right at contact due to "hook effect".

This means that handpath is one thing and bathead path another and difficult to measure length/spatial aspect of swing as well again related to difficulty identiofying a "launch" point.
