Hi Don,
There has been quite a few posts about the lady's heel turn (1-3 Rev). The alignment although written has 1. Backing DC. will almost end backing centre. Not too much importance should be made about that. It does start backing DC but at the e/o 1 it's almost backing centre (toe turned in). This turn is inherent and should not be taught. There are 4 fundamental movements in ballroom dancing, which are: The Walk; CBM; Rise & Fall and Sway and alignment is not one of them. There is no noticeable foot swivel between 1 & 2 of the Rev for the gent. Lots of teachers, besides myself, teach, starting with a Feather, 5 forward walks and then turn on the RF. Here is another tip. Rise & Fall. Dance under the floor then on top of the floor: NOT OFF. Apply that to the 5 walks and notice how much more you have travelled.
