Observing at 150 Mpc and have been Locked for almost 3 hours. About 2.5 hours into the lock I noticed that the DCPDs were diverging. Since this happened yesterday (87842) and had been due to violin mode ETMX mode 6, I first turned the damping off for that mode since yesterday trying to damp the mode more made it ring up more (but also brought the DCPDs back together??). This clearly didn't help since the DCPDs started diverging at a faster rate, so I've slowly been upping the gain from its nominal gain of 5, to now 11, which seems to be damping it. I'll probably bump the gain up a bit more to get the DCPDs to start converging.

As expected, the time from finishing the MAX_POWER state to when the DCPDs visibly start diverging yesterday's lock vs today's is about the same, 2hr 37mins-ish (yesterday's lock, this lock)
