"Extensor action has nothing to do with the flying wedges, there is no 'longitudinal alignment' of the left arm and extensor action has nothing to with the loading and the right elbow position. Thats TGM sludge. FACT!"

While perusing my attention was drawn to this statement. The idea that extensor action has nothing to do with the flying wedges. The way I see it (happy to change that to "saw it") is that creating the 90 degree relationship between the LFW and the RFW at fix determines the amount of right elbow bend. Do you not need a bent right elbow in order to attempt to straighten it against the checkrein of the left arm? Also doesn't extensor action ensure, or help ensure the correct degree of elbow bend at top?
So by the constant effort of straightening a bent right elbow, my left arm is extended, that resultant left arm extension then is what determines the degree of right arm bend. I thought I knew what extensor action was!!!


The flying wedges and my selected plane determine the amount if hip bend (assuming a normal knee flex)
The on plane right forearm determines the amount of elbow bend at fix
The checkrein of the left arm determines the suitable amount of right elbow bend from startup to follow through with maximum radius
