"resistance to the deceleration of impact"...a primary concern of the hitter. As we are in the Emergency Room for Hitters, snap releases are TABOO! No maximum delay for me. Horizontal hinging would give me the heebie jeebies.
In the case of hitting isn't the primary hand speed generated by the driving of the right foream and shoulder as hard as you can through the ball using the proper hand positions.Similar to the blow I would use in hitting a punching bag.
