I take no credit for this. I was simply at the lecture and I just passed the information on. Something to add to this. Foxtrot Reverse Turn Step 4 the heal lead for the lady. Turn this slightly to the inside. The man who is moving backwards. curve it very slightly to the centre. Doing it this way moves both feet onto the same alignment Instead of one pointing west and the other east just prior to the feather finish. Give it a try , see what you think. This info is again from a lecture which I attended.
