I am saddened that you think I would have made a hash of that and amazed
that you could think I had never have come across such a thing
before. :-(

I would have thought that

  "Consider any ordered measure that "wraps round" -- bearings in
  degrees, minutes in the hour, indeed hours in either the 12 or 24 hour
  clock."

might have suggested it was not any old start <= x < end problem.  How
would you have phrased it so as to avoid the confusion?

Anyway, the take-away is that the size of the range is not part of the
problem and that no modulo operations are involved.  I found that mildly
interesting.
