In Jack's instructional DVD he states that the circular hand path contributes to 40-50% of batspeed. Are THT and BHT the only other components to batspeed, and if so what percentage contribution to batspeed would be attributed to each?

> "the circular hand path contributes to 40-50% of batspeed." I am not aware of any independent study confirming this is the case. Maybe it's true but it has not been proven. For the THT and BHT stuff, well...THT is a technique to assist the hands in starting in a CHP. BHT is a term that means different things to different people, because it has not ever been clearly defined, other than it has something to do with the hands rotating the wrong direction.

> Thanks, but I am trying to get at something a little bit different. Say for example a hitter with good rotational mechanics can generate 60 mph batspeed. Of that 60 mph, how much of it comes from rotating the hips and shoulders, how much comes from using top-hand torque to get the bat moving around, etc.? Given someone's strength, what all contributes to his/her batspeed?
