Now looks improved (compiled from commit 4b753dc7 src):

Measuring the real voltages shows input.voltage is reading high by 2%
and output.voltage low by 6.5% (real voltage is 243.8V and output 244.2V atm).
The measurements reported by the UPS seem to vary quite markedly
between invocations of upsc so I can only assume the A/D used has only a few
bits resolution or the sample window is small.  On bypass input.voltage
should = output.voltage of course.

I agree!
