Hi, Nick,
No whacks intended! It was an easy catch because I was mulling over
similar problems with my code. My own second pass at a vmode
implementation for Calc is below, now with support for negative values
and bimodal data. It takes a different route and is a bit shorter, but
doesn't hand

Yes, this is an off-by-one error: in vfreqs, I should cons prev onto
freqs, not (nth 0 vec). In addition to this and
Hi, Nick,
I think your vmode() needs to subtract one from the result. The mode
in the "systolic" column of Jude's dataset should be 124 (f=12), not
125 (f=2).
For Jude's limited purposes I got by with less code (but note the
caveats):
