[HungryBear]

As I understand it:
The flw is the angle in the primary lever at the left wrist. notice I do not say cocked because the wedge exists until #3 accumulator reaches zero (uncocked). that will not happen until both arms straight at followthrough. but. the wedge is flat to the left wrist at impact(level also-don't confuse). How it gets there is a function of hinge action . Cocked at release-level at impact/or low point-uncocked at follow through. always flat

2-P wristcock

I think your instructor is exactly right.
