Another thing to consider is progressing on to the next. Chinese Fan
is fuzzy about where moves end, as the star turns. So you need to have
dancers promenade "to progressed places", rather than just circling
halfway or some such. I've found dancers have great trouble with this,
at least partly because 4-face-4 is an uncommon formation, so they
can't just progress by autopilot.
Some of my biggest and most memorable crashes when testing dances have
resulted from this problem.
