Subject: DRMI tweaked, briefly held with ALS arms 

Given the RF component power supply grounding, POP110, POP22 and REFL165 all changed somewhat. They have all been rephased for the DRMI, as they were before. 

I tweaked the 3F DRMI settings, and chose to phase REFL165I to PRCL, instead of SRCL as before, to try and minimize the PRCL->MICH coupling instead of the SRCL->MICH coupling. 

With these settings, I once locked the DRMI for ~5 seconds with the arms held off on ALS, during which I could see some indications of neccesary demod angle changes. Haven't yet gotten longer, but we're getting there...
