And all day, for the last two days, I haven’t noticed a single ES on any of my four lines. That involved looking at 30 min snapshots of all lines ever few hours, as I was trying to test a change in my software to do with the reporting format. So that report was, I’m afraid, untypical. Looking at the raw data for line 4, for example, I do see 5 ES downstream and 2 up, in 24 hours.
