What P? You don't believe you should LAG the barrel as long as possible. Then turn your hips. Then turn your shoulders (cause resisting is a falicy) holding the hinge angle. Then throw/hammer the barrel through the ball, when you decide to hit the 100mph fastball?
IMHO, you should keep the barrel Up as long as possible, holding resistance, and the barrel should go right towards the ball, not torqued back at the catcher.
The barrel is held up longer, on an inside pitch, more so than outside.
The tilt, takes care of all the swivel drivel.
