DG,

Now that the video is up and we've had a chance to review it, Lynn posted that it is a left arm swing with the "magic of the right forearm". Do you agree?

It's a faulty left arm swing by default, because it isn't a right arm swing nor a hitting procedure. There is no initial shoulder thrust, but rather the right hand is moving the left arm. The hands are overaccelerating causing #4 accumulator throwaway and there is wristcock throwaway.
