- Ok, time for some fun square-dance dweebery.
-
- Give each call a point value corresponding to its level. A Basic call is one
- point, Mainstream 2, Plus 3, Advanced 4, C1 5, C2 6, C3 7, C4 8.
-
- Find the set of calls, sufficient to convert any symmetric parallel wave
- formation into any other symmetric parallel wave formation, that has the
- smallest sum. You can't leave waves (i.e. sequences of calls that move you
- out of waves and then back into them are not allowed) and you the calls must
- not be modified (i.e. no "ladies trade" or "ends trade").
-
- The best I can do is 7, and involves no calls above Advanced. If you remove
- the "no modifiers" rule you can get 4.
