House number interpolation does not work for one particular way about nominatim HOT 4 CLOSED

Some of the search strings I'm using for testing:
9396 avenida guaíba
9996 avenida guaíba
10000 avenida guaíba

from nominatim.

Nominatim has a sanity check built into the interpolation code and cowardly refuses to interpolate more than 1000 house numbers at a time. That seems to be the right behaviour in the example above. You are trying to put 700 house numbers on an 80m stretch of road (1000 even if you take the second interpolation into account). That can't possibly be right. You shouldn't be using interpolations in this case but individually add each house number that actually exists.

Thanks. I think this should be on the FAQ along with other sanity checks.

You are right, there are not 700 houses in such a short length of the road. Unfortunately, mapping individual houses would be too much work for a single person to do. Interpolation can also provide a "reasonable approximation" and be resilient to unnoticed changes. The range of numbers is large in this particular case due to poor administration; fortunately it doesn't happen in other areas.

The computation of house number interpolations has changed. Example seems to be working now.
