To Rha. I am not sure what you meant by my option. To continue the discussion . According to the technique book there are several places where the term NFR occurs. First step of the Feather in Foxtrot for the lady, and for the man in a Reverse Wave.Or in a Quickstep for the person moving backwards immediately before a lockstep.It seems to me that it creates a moments delay, which allows the person on the outside to slightly overtake.( for want of a better expression ).Teachers seem to avoid this part of dancing like they would the plague.Which is a pity for somewhere down the line it is going to become important if a couple are going to dance as one, and not come apart on that particular part of their dancing.
