Here’s an example:
I got this email the other day, about my percentage of running Beacon Hill, which apparently is in Boston. The last time I ran there was in Dec 2023.
Me getting this email feels like a bug.
Those can be sent if the city is updated in a way that adjusts your percentage.
You shouldn’t get multiple emails for the same percentage completion, though.
This may have been my “fault”. I recently made some OSM edits in Beacon Hill, and I think the net number of streets may have been reduced as a result (and hence your percentage went up).
