> With efficient mechanics, the angular acceleration of the bat stays in sync with the rotation of the shoulders. Therefore, their bats arrive at contact as shoulder rotation is depleted. With less efficient mechanics, the bat remains 30 to 90 degrees from contact (bat drag) as shoulder rotation ceases. Once the shoulders stop rotating, the only muscles left to power the bat to contact is the smaller muscles of the arms.

Jack,
Seems like other things are depleting simultaneously.

The elbow drops, then "stops". Which causes the forearm to advance without effort, then "stop". Which causes the bat head to advance without effort past the hands.
