"Borrowing" is simple: it works for any number of 3-couple sets and
one 4-couple set forming one long row (but usually you have just 7,
rarely 10 couples). Dancers stay in their own set; no "stepping
down" to 4th place except in the 4C set at the bottom.
On the first and all odd rounds, three couples of each set are
dancing, the 4th couple of the bottom set stands idle.
On the even rounds, the top couple of the row stands idle, and
each other set "lends" its top couple to the set above, where they
end in 3rd place of the dance, and immediately become the 1st
couple for the next round in their own set.
If the dance is 8 times through, the 1st couple in each 3C set twice
dances as 1st couple twice through.
