Anyone else experience similar drops in heart rate whilst

No. Never.

Me neither, and I'm skeptical your HRM was correct.

I???ve had my HRM lock onto a harmonic of my heart rate if the
strap was too dry (ie: actual heart rate is 75, HRM reads 150).
Once I start sweating, it will usually fix itself, although I
may have to pull the strap off my chest for a second to force
it to reset.

I've had similar harmonics, but usually resulting from a mild
arrhythmia. Specifically, from time to time I've had occasional
runs of premature atrial contractions, and it shows as an increase
from the low 150s to 227 or thereabouts (the max the unit can
register, I think).

Seeing a rate *lower* than resting wouldn't be a harmonic, but
maybe there are beats being missed by the unit and it's reading
low as a result?
