I've tested the addition of +30deg phase on ITMY ROLL and for this lock I saved F6 in SDF, but ran out of time to modify guardian.

  • not sure if this is significant, but I've been noticing peaks in SRCL, and they come and go
  • they were there in the first lock of my shift, but are not there now, the last lock of my shift
  • snapshots attached, lock with peaks first, then current lock

The new filter worked well for me as well. I added it to ISC_LOCK
