LiveBPM indeed does not do well with waltzes. No problem with jigs or reels.

I don't know whether anyone has done careful
systematic testing of liveBPM's accuracy on a varied range of contra dance music. If
anyone does, I'd be interested in knowing the result. I have, however, seen liveBPM
be seriously confused (if you'll pardon the anthropomorphism) about the tempos of
waltzes, where the beats come in multiples of three. I wouldn't be surprised if it
could were sometimes similarly inaccurate about jigs, in which the beats subdivide in
thirds. For example, perhaps it would sometimes report a tempo of, say, 84 BPM for a jig
whose real tempo is 84 * 4/3 = 112 BPM.
