BRS Y --Continues to Drift and will need recentering before long
Here are trends of the BRS raw balance position: a 12 day (right) and 30 days, left. The driftmon has a range of +-16000 so at -13000 and still trending we don't have much room. At the current rate, we'll reach the limit in about three days.
