It's easy to conceive of a device which, for whatever reason, gives
an "absolute" reading accurate 2C, but which tracks temperature
changes somewhat more accurately. And hence a small difference
between successive readings still has significance. A real-world
example is a mercury thermometer in which the glass has been
physically shifted relative to an adjacent scale. So 18C reads as
20C, etc.

Cheers,
