jj, not sure if this is what you're looking for, but it's a problem area more related to keeping the beat and staying on time. I am pretty good at this in every dance except the Vienesse Waltz. Not sure why, other than I know the bpm is faster and maybe I just can't keep up over the long haul of a 3- or 4-minute song. I keep up in terms of getting through the dance, but if anyone was really paying attention, they would know that I was off with rhythm and tempo at least part of the time. I do OK in shadow practicing, not so hot with a partner. As my instructor has said a few times, probably only half-jokingly, "you're really great when you dance by yourself."
