Inertia: Resistance of any physical object to any change in it's state of motion, including changes in it's speed and direction.

The high level swing consisting of pull backs against the leg leading to the eventual rearward whip of the barrel have already defeated inertia PRIOR TO THE GO DECISION....and the barrel is simply released.

The forward push swing, has to defeat inertia AFTER THE GO DECISION.

WHEN inertia is defeated is the difference between sudden and slop.

Manny defeats it BEFORE go. Suddenness of launch results.



The kid has to deal with inertia AFTER the go decision....
