So, does anybody know why anyone would incorporate a #3 accumulator angle when swinging if a snap release and a small pulley provides maximum power? Shouldn't this angle be avoided?

And, when hitting, is this angle beneficial in some way? Should it be incorporated into all hitting procedures?

The Swinger greatly increases the Lag and produces a sharper, smoother Release Motion by bringing the #3 Accumulator into Impact with a Turned Left Wrist (not Vertical). This is the Left Hand Karate Chop -- palm down to the Plane -- through the Line of Sight to the Ball before the Release Trigger. The simultaneous Right Hand Karate Chop brings the Turned Right Hand (with its palm up to the Plane) through the Line of Sight to the Ball before Triggering.

Though the Hitter does not normally employ the Snap Roll into Impact (Release Swivel), he nevertheless benefits from the Overtaking Action of the #3 Accumulator. Accordingly, as you suggest, he should incorporate it into those Strokes requiring more than minimal Power.
