Hey Jack

Point taken with your swivel handle bat but that only produced 60+MPH of speed but what would give the bat the rest of the 20-30MPH that is produced in a full swing of a bat. Though your experiment gave you a speed produced by CHP and torque it did not give you the total batspeed that could be generated with a full body movement. Therefore the really statement is that bat speed produced by CHP and BHT is equal and when added together produces significant batspeed but not 100% of the batspeed. The accumulation of all movement that influences the motion of the bat produces the final batspeed rate.

Numerous experiments would be required to determine exacting what body parts help to accelerate the bat though the processes of CHP and BHT.

Did you find the article about the golf club speed interesting and how it would apply to hitting a baseball?? Wrist cock and release close to contact was significant and if you think about hitting a baseball the same applications hold up with the difference being ideal hitting location in it relationship to the ability of the batter to get the longest period of time that BHT could be applied. The longer a person can apply torque on the bat the larger the impact zone cold be.
