Hi Jim,
in addition to "liveBPM", I also have on my Android phone the app
"Metronome Beats". I use it to tap out the tempos and also to compare
the results with liveBPM. I found these two apps to be reasonably close,
at least for jigs and reels.

I'd expect a contra dance tempo in the 80s to feel not merely slow, but excruciatingly
slow, especially if in the low 80s. To get an idea, try playing one of the Youtube
videos in the slower half of the list I posted on Wednesday afternoon, and then use
YouTube's "Settings" control (click on the gear-shaped icon in the strip at the
bottom of the YouTube viewing window) to set the playback speed to 0.75.
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.

Sometime over past year someone use liveBPM at the Nelson Monday night dances a
few times. It was interesting to see that the beat per minute varied quite a
bit depending on musicians, dancers, the caller, and particular dance. They
varied from a low in the 80’s up to about 125.
And, yes, the music seemed slow with bpm in the 80’s, but it worked well given
the dancers on the floor.
