Day 15 Timeline 1/31/20
Link to OP
Red line is 1/31/20. Yellow is presumed downtime. Blue line is today (2/1/20).
Yesterday was not the best day for RotR. While they called up to BG 110, which is a little more than average, there was a fair amount of downtime, especially in the morning and afternoon.
