TfL aren't interested in how long it takes *you* to get to the top

or even how much opportunity for exercise it gives you

what they are interested in is, making sure that the crush at the
bottom of the escalator has gone by the time the next train pulls into
the platform

Which when I was at Baker St last week (which has a fairly short
escalator) it wasn't [the crush disappearing before the next train
arrived].
