Particularly important is your observation that it is usually taken into the Address Waggle area. The Address Waggle is ideally an Arms Motion that reacquaints the player with Sections 8-9 through 8-11 of the Stroke -- Release to Follow-Through -- in both directions. The Start Down Waggle is an Arms and Pivot Motion that Transports the Fully Assembled and Loaded Power Package Down Plane from the Top into Release.
Overlapping the Address and Downstroke Waggles allows the Player to remove all cobwebs and restore full consciousness of the Downstroke.
