For example my max distance didn't seem to be sufficiently low and I immediately found two garages that got an address incorrectly: <a href="https://osmcha.org/changesets/104271458">https://osmcha.org/changesets/104271458</a> -- the best case scenario is when every selected element of the reference has exactly one obvious subject to conflate into. I did a lot of ctrl+z, ctrl+shift+z to double check what I was about to upload and still missed a couple. The next obvious step would be to remove or merge address nodes that duplicate the buildings underneath them. There's a bunch of address nodes that are floating without a building underneath, that should be taken care of shortly with my Sonoma import.</div><div><br></div><div>Overall I'm happy to see OSM's usability quickly improving in the bay area!<br></div><div><br></div><div dir="auto"><br></div>

Alright, good to know.<br>

I'm manually resolving the building address conflicts I missed when I first did my import, but I'm realizing that merging addresses with unaddressed buildings will be a lot of work and I'm not sure its worthwhile to do manually. So I'm interested in whatever automated coalescing solution(s) you come up with.<br>
