In short, simultaneous full release of both pa2 and pa3 right after transition, upon reaching early elbow plane. You think this is possible? Any experience hindsight on this?
The Simultaneous Release -- the straightening right elbow driving both the Left Wrist Motion (Uncocking) and Hand Motion (Rolling) -- is a Hitting procedure per 4-D-0 and 7-1. This Hitter's "overlapping" of Power Accumulators #2 and #3 increases Thrust, whereas the Swinger's non-overlapped "sequencing" increases Velocity (6-M-1). The simultaneous application of Power operates as "batteries in parallel" (versus the sequenced "staged rocket launch").
