...L arm not inert at all...it is firing hard from L shoulder to hand...all Roll...all PA3...
It should be inert! - the Left Flying Wedge rolls(Throwout) because the left shoulder is moving off plane, being driven by the right shoulder. Rolling the left wrist gives Hor. Hinging and is completely independent of Throwout. Hinge action of the left wrist doesn't mean the left arm is "active".
