Screenshot of the SCAN_SQZANG state (76776) - it scans SQZ CLF RF6 demod phase to scan the sqz angle, and optimizes squeezing at 350 Hz by minimizng the yellow BLRMS3.
Here it changed the CLF_RF6 demod phase by +19 degrees. That was a squeezing improvement of 1.4dB for 350 Hz yellow BLRMS 3, and improvement of about 3dB for the 1.7 kHz blue BLRMS 5.
