As the 3R10 BLM that was causing us grief is above the late 5R beamline (always take a look at the pictures on the ops wiki!) we began nudging the vertical orbit in this region downwards, away from the BLM. Though the BLM readback didn't budge, this seemed to benefit us in the earlier portion of our shift and we left it alone until about 2100 when we began getting 3R10 trips once again. At that point we decided that more substantial adjustment was necessary so we carried on with the same tack as before and eventually got the readback to drop a good amount.

At the start of shift, while looking for reasons that ILM3R10 might be tripping us up I noted GLDER alarms for 2L04-7 on the General Tools Screen and found that this cavity was quite noisy indeed. A smidge of steering at the start of shift seemed to take us off the edge for 3R10, but it showed back up arond 2100, so I decided to take a look at this cavity. Shortly after derating it 0.5 MV/m it tripped off and the Crew Chief gave his blessing to do a lil tune-up. Turns out the DETA was zeroed about 40 degrees off. It looks much happier now!
