I can see from H1:ODC-OBSERVATORY_MODE that there appears to be about 70 minutes of commissioning today even though in reality there was zero.

Please only use

H1:ODC-OBSERVATORY_MODE = COMMISSIONING [40]

for commissioning.

Don't use it for tasks that are CORRECTIVE MAINTENANCE [53] in nature, e.g. fixing problems when IFO doesn't work, even if the commissioners are working on that problem.  That's no different from EE shop trying to identify and eventually replacing broken electronics.

Commissioning is a planned detector improvement project (IFO characterization measurements, noise and/or stability and/or lock sequence improvement etc.). When you find it on a whiteboard for commissioning tasks, that's commissioning.
