While investigating some recent beam jitter, found that the 2A SLM centroid was not being recorded in the archiver. After some digging, the Stats plugin was found in Disabled with the Compute centroid field set to No. It appears during the mass ioc reboot that occurred on 06/02, an undesirable restore point was used. Centroid is now being actively updated again.

Not bad, but things will get more interesting when Hall C goes to fourth and then fifth pass. 80 uA to C on fifth pass and 3 uA to D tagger dump would total 893 kW :-)
