>>> This force creates a torque about the wrist joint, being the product of the force on the bat created by the top hand times the lever arm of that force, i.e., about 3 inches. <<<

Hi JJA

I would say the lever arm (center of the left hand to the center of the right hand) is closer to 5.5 inches. However, regardless of the lever arm measurement, tests show that 45+ mph bat speed can be generated by keeping the right-hand in a fixed position and applying BHT alone. This bat speed is generated independently of THT or any "flailing action" from a CHP.
