I had trouble locking the IMC yesterday when increasing the input power.  So we measured the OL TF at the Common Mode board and found that the UGF was about 100 kHz with maybe 20 degrees phase margin while locked at 1 W.  So we changed the guardian common mode gain calc by -4db to get a little more phase margin and match what Kiwmau's suggestion was in aLOG-36354 of about 50 kHz nominal, it now stably working at 10W.  I've attached the plots of different power levels input into the IMC.
