Thanks, I'm doing fine, except that it might still be spending too much time on the project ;) Hope this finds you well too.
Pages at Wikipedia that have an item associated with them can directly use properties without specifying the item they draw the information from. This may explain why the map works in an article, but not on the template documentation page.
enwiki did some experiments on how to use quantities, see w:Module_talk:WikidataIB/sandbox/testing#Scaling_quantities. Maybe these can be made to work.
