This entry is a followup to: 88776
at end of test, we go from 25% fan to 20% fan (47.7 Hz)
and PID output goes from 70 W to ~ 290 - 330 W, so the
5% change makes a 220 - 260 W difference.
JP thinks this is an inordinate amount of power dumped into the
LD2 target, and maybe indicative of fan problems to follow. He suggests
we run at reduced frequency, like 20%.
