I found slow and quick very confusing. It always made me think I was to move slow or quick. When actually body movement is a constant speed. Lot of the quicks come from taking 2 steps ( side-close, chasse, forward-lock etc.. ) to move your body the same distance as other steps do.

1 and 2, 4 and 1, etc worked much better for us.

The practise of quick and slow is a real killer for Russin teachers. boistra boistra merelimbda in swing or chacha lessons is a killer for the teachers. I probably have the words a bit wring, they have to say them so fast, it is hard to understand them
