Jolieboy,
When you hear about the 0.7 secs, this is time to the plate with runners on base with a slide step, which is important for holding the runners but actually messes up mechanics.
I know my son's previous pitching coaches talk about "tempo and intent to throw hard" but I have never heard anything about timing drive to contact point. Not that it might be important, just never heard about it and not sure what and how you would change behavior based on a series of measurements.
