I agree. You can say the words "Slow-Quick-Quick" and it will not make you dance that way at all. Counting 12-3-4
will make it happen. I remember when it was a big ah-ha too learn that a slow has two beats. It does seem to held one move more slowly in Quickstep to say the words "slow-slow- slow & slow".
In my opinion, it is a waste of time to define rhythm as slows and quicks.
