Is this @My_Metro stat misleading? Does "escalators were working" mean:
- every escalator was working
- every station had a working escalator
- every station had working escalators in both directions
- they measured time each escalator was running, and took the mean

The first two options are straight out, because one of the escalators at Haymarket has been broken for weeks. And if it's the mean, should it be weighted by usage?
