Aha – I think that must be it. I retested with a new Mayfly, and its reported voltage agrees with my multimeter within 0.1V. The old Mayfly (s/n is either 180080 or 190080) was probably purchased in 2018, and has been my desktop tester, almost always under USB power, so didn’t detect any problems until now.
Thanks @shicks!!
