Yes, but we were talking about the postcode predictor were we not?, and
that is inherently inaccurate because a postcode can cover quite a large
area.
Hmmm. I suspect it is rare for a postcode to cover more than a small street
or a row of houses on a large one. I would think it particularly unusual to
cover a wide range of elevations, unless the street is extremely steep.
