When I try to translate and describe the feel I associate with proper acceleration I think of a rocking-like effect - not a swaying motion, more like the weight transferring down through the right foot into the ground and then rocking back to the left, planting the left foot, BEFORE the top of the backswing. An exaggerated analogy would be cracking a whip - you must start forward well before the whip completes it's backward progress or all power is lost.
Does that sound right to you, Daryl? It's almost like the sequence I'm describing must be standard procedure on full shots or loss of power (and fat shots) will result?
