Who believes the components in section 10-20 are down stroke triggers...or what starts the downstroke. That starting the downstroke with the lower body is not correct?

10-20-A Hands Trigger
10-20-B Right Arm Trigger (right forearm)
10-20-C Right Shoulder Trigger
10-20-D Muscles of both forearms trigger
10-20-E Left Wrist Trigger

The five Component Variations listed in 10-20 are Release Triggers, not Downstroke Triggers. As such, they are not active unless and until the Start Down (8-7) and Downstroke (8-8 ) requirements have been met.

For the record, the 10-20-D Variation is the Delivery Path Trigger, not "Muscles of both forearms" Trigger. The latter designation does not exist in The Golfing Machine. Per 6-B-2-0, the "muscles of both forearms" are available to actuate the Release of the #2 Accumulator (Left Wrist), but this would apply to the Wrist Throw (10-20-E) and not the Delivery Path Throw (10-20-D).
