Thank you for all this advice! To answer some questions:
We did have a loop installed, with a dedicated return line (and therefore we don't have one of those black sensor valves under the sink). This hot-water recirculation pump was installed at the same time that we were doing a whole-house copper re-pipe, so it was cost-effective to have a loop installed . My understanding was the loop was installed to BOTH bathrooms (the master bathroom and the guest bathroom), but honestly I haven't really confirmed that guest bathroom is indeed in the loop.
I will do this first-in-the-morning test tomorrow and report back the results!
