>>> I recently purchased the Final Arc II video. On that video it states than about 1/2 of your batspeed comes from the circular hand path and 1/2 from torque. I made a "torqueless" bat as shown in the video in order to separate hand path and from torque. I can get 60-65 mph batspeed using the torqueless bat into a heavy bag. However my batspeed using a real bat is only 80-85 mph. This means I'm getting 3/4 of my speed from the hand path and only 1/4 from torque. Is this within the normal range of proportion variability? Or should I be getting 120-130 mph total speed based on my torqueless bat speed? <<<

Hi John

It is not surprising that you were able to attain a 60 -65 mph torqueless swing. In fact, given enough time and long enough hand-path, speeds approaching 80 mph has occurred with one hand. But with the hand-path (and time frame) generated with the actual two handed swing, speeds in the 40-50 mph range are more the rule.

On the other hand, linear transfer mechanics that develop 65-70 mph may generate only 15-20 mph hour from the more linear hand-path. This means that the torque factor accounts for about ¾ of the bat speed for batters with a straighter hand-path. Therefore, extending the top-hand during initiation limits the bat speed that can be attained. --- In the video I made the point that one of the key factors in generating maximum bat speed was to maintain the most optimum hand-path while adding torque to the swing.
