"Point of Origin" in 10-20 refers to the originating point of the Action that Triggers the Release. In other words, the locushttp://www.merriam-webster.com/dictionary/locus of the Triggering Action. Is that locus the Hands (10-20-A)? The Right Arm (10-20-B)? The Right Shoulder (10-20-C)? The Left Wrist (10-20-E)? Or, for Automatic applications, the end of the Delivery Path (usually in Combination with either the Right Arm or Left Wrist / 10-20-D)? Or in some other Combination (11-20 lists some, but certainly not all)?
The quote emphatically does NOT apply to the three Release Points (Sweep, Random and Snap) or Release Types (Full Sweep, Random Sweep, Snap and Flip). While the Variations of the Trigger (Component #20) and the Release (Component #24) are ordered to reflect their parallel nature, the Release Points and Types are specific to the Release Component (11-24).
I continue to post in this thread because I believe there is value in refuting -- by differentiating with the facts and appropriate references -- the misinformation attributed to Tom Tomasello by his most ardent proponent.
And I'm sure I won't be the last ardent proponent.
