I believe that zig left, zag right normally takes 4 beats. If the
dancers zag a little farther so men can easily take a left hand that
would take an additional 2 beats for a total of 6 counts. I'll
confirm the timing this Saturday.
For me there's this issue of how much we ask the dancers to adjust.
It seems that asking dancers to adjust is common in English and
perhaps less common in contra.
