Jack,

First of all compliments to the site, I think we can all agree scientific approach to hitting helps us all. I've been reading for a couple of months now and think you're spot on.

I do have a discussion point, which mostly come from naming and labeling various theories.
The linear approach mostly states crack of the whip effect. This approach is, offcourse, not used by any baseballplayer making great batspeed. What I do believe, is that the crack of the whip effect DOES happen. Not the way it is being explained. Let me explain. Get yourself a towell and give it a whip to get the best "crack" you can. Then analyse the path your hand takes.
This movem is not a linear movement which stops at a certain moment. Is is a "loop". By the, like you call it, negative move, the towel (or baseball bat if you will) accelerates explosively.

So what do you know, the crack of the whip effect does happen in a rotational baseball swing (CHP). It also happens in a linear swing, but offcourse a lot less. High school science is the best i've got on this, but isn't this (I don't know the correct english description) slowless of mass? (when you drive a car and crash into a wall your body doesn't stop as fast as the car but keeps moving forward aka slamming your face in the airbag)

Nice holidays everyone!
