I call regularly at 3 different dances that are multi-caller. None of 
them keep any records of the dances called, to my knowledge. But the 
callers are mostly very flexible. I certianly come with a few 
possibilities to chose from, depending on the crowd and the previous dances.
At the Nelson dance, I often follow Don Primrose calling Chorus Jig. 
When that happens, I simply plan to call a dance without contra corners, 
and I seldom pick a chestnut either. I do remember at least one time 
when I and my predicessor had both seen an interesting dance to try (on 
this or the other callers mailing list!), and we both planned to try it. 
As i was second in line, I lost, and did something else. Otherwise, I 
simply make sure that I don't call a second instance of a hey, contra 
corners, petronella turn, wavy line (in either direction), and very few 
others right after the same thing. But if one of these hasn't been done 
yet, it's a good possibility for me to try.
There are so many dances available, and callers are usually dancing when 
they are not calling, so we always get a good mix of dances. The one 
time when this might be an issue is when there is a new, beginning 
caller in the lineup. But this is a teaching moment to talk to them 
about before they are at the mike, to help them pick a dance that is 
right for the crowd, and their slot in the sequence.

 caller using the same dances or ones that are similar. 
 Our dance is multi-caller, and our standard procedure is to have the 
 night's callers fill a spreadsheet with their anticipated dances (not 
 cast in stone) including all the moves, so everyone knows when they 
 are going on and we can look out for too many in a row too similar. 
 Last dance, we got a little tight on time and the spreadsheet had only 
 titles. We ended up with 2 dances exactly the same under different 
 titles. Some dancers noticed, some didn't.
