I do not know what is the best possible accuracy but an altitude measurement rounded to 0.1 meter or 0.5 feet seems IMHO reasonable. I have never seen a sign with more precise information.
you can even put a measure 10 times more accurate, this will remain very far from your example but still allowing to find a round number after conversion. _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
