If Tomasello didn't TEACH the RIGHT ARM SWING...then he taught 12-2-0 as it was written with/per 10-24-B with Non-Automatic Right Arm Throw Trigger...whatever you guys want to call it...all I know it works...Right Arm accelerated swing.
However, I think you're wrong...the focus of the swing is on levering (cocking) and unlevering (uncocking) the right elbow.
