"Anonymous. When I wrote about having the feet apart and the weight being passed from one side to the other I had in mind 4 5 6 of a Reverse Turn Foxtrot. And being balanced on 5 before I place 6. "
That would be a serious mistake!
You do not "place 6". You body moves through five, from being unbalanced short of it, right through being balanced over it, and on into being unbalanced beyond it. During that time, the free foot swings across the body a small distance, but also moves a quite large distance, as it is being carried along with the body.
If you just look at a plain feather on a good English-type champion, you will see that the 2nd quick is about 2/3 the size of the first. On a student who did not sustain body movement and merely swung the foot across the body, it would of course have to be much, much, much smaller. But on a champion who moves the body a lot during this step, plus the foot across the body, the end result is a lot of travel. And only for the briefest instant at the peak of rise with the body over the left foot is it in balance - the rest of the time it is not. Watch video of someone like Hawkins frame by frame and you will see.
