One point I want to bring up is that full extension is an ideal. Going to full uncock is certainly a very close approximation from the level left wrist at impact however in some strokes which are mechanically less than ideal this may not be the case. The wrist motions must comply with the angular motion taking place on the inclined plane... which dictates exactly how uncocked the left wrist may be.

Also you do not go to a full wrist uncock at followthrough except for angled hinging.....
