Some comment on these concepts so far.
All 4 couples
You say 4-dancer calls. What about 2-dancer calls. All 4 Couples 1/4 In/Out
is called by some callers? Should I interprete your definition as it should be All 8?
"Dancers execute the given call, usually moving around the outside of the set."
Maybe you should emphasize that it usually starts like that but might continue
through the center as in Square Chain Thru.
In All 4 Couples you say that All 8 has the same ending rules. That is not
explicitly mentioned in All 8. You have for example from a Thar, All 8 Turn Thru where you have to adjust.
