I think this debate always gets sidetracked by the difference between preparation and backswing. Prep is what the MTM'ers call "stalking", the unit turn with the racquet held in front of the chest area. Backswing is from this point where the hands split- from here there should really be no pause (assuming the hands have split high). For a player who has a straight back take back there will be a pause in the transition from back to forward.
