entry = Unwrap The {formation}
Message = The example with "Unwrap The Diamonds (from Facing Diamonds)" does not seem to follow the definition. Consider the boy dancer #4. After the first circulate, he meets the condition for:
"Other dancers do formation Circulates until reaching the lead dancer's starting position & then walk straight ahead to follow the lead dancer."

He is in the lead dancer's (girl #4) position, so the definition says he should walk straight forward. His orientation is the opposite of her initial one though.

Boy dancer #3 has a similar odd interaction with the definition. After 1 circulate he is in a plausible position where, if the leader had started here (she didn't), then he would continue forward. For some reason he continues forward anyway.

The callerlab definition is consistent with your text. It seems a good thing to fix that. Switching from circulating to walking out to the column is a function of being a trailing point, not of being where the initial trailing point was.
