Responding to a couple of points:
If you don't like saying "beats", say "steps":
"You usually have 8 steps for a circle, for this one you only have six
steps".
To get them round a circle faster without going into too much detail use
phrases such as:
"You need to get around this circle a little faster, you'll find it easier
if you put your elbows down and your hands up" - demonstrate - this tends to
make the circle smaller and increases connection so the better dancers have
a chance of pulling the slower ones round.
Happy dancing,
John
