unhelpful. I have lost count of the people who look at the one at my
local stop and then come away mystified as to when their next bus will
turn up - this is because it says something stupid like every 9-11
minutes rather than actually tell them buses come at 07,17,27,37,47 and
57 minutes past the hour (which is what the real contracted timetable
does actually say).


Does every route have a specified tmetable like this? To be honest
I'm glad that the exact times aren't given on most routes in inner
London during the daytime, since the buses can't stick to them very
closely. (Night buses, and infrequent suburban buses are a different
matter).
But saying buses run every 9-11 minutes is equally bizarre, since
obviously there are plenty of times when you get two buses together
and then nothing for fifteen minutes: 'every ten minutes' is a more
sensible thing for the timetable to say, since '9 - 11' implies
greater accuracy. What is one to make of a timetable that says buses
run 'every 8 - 12 minutes' at some times, and 'every 9 - 10 minutes'
at others?
