I've updated the address data on http://qa.poole.ch/addresses/ch/
to the current GWR address data.
There is one, larger, change from the previous update (mid-2019).
As it seems to be a trend to add ancillary buildings now with
house numbers in the format number.number I've
removed them from both the statistics and the generated files,
this removes a good 200'000 addresses from the current dataset
(note if somebody wants this data I can generate files with them
included).
This, naturally, doesn't address the problem with non-postal house numbers and the different ways of handling them in general, put should limit the effect it has to the places and cantons that are not using a numbering scheme that doesn't differentiate these in format.
