E.g. several runners on Hunts Point, WA show 100% completion, but some are ranked 2nd place. It then shows things like 100% completion, 10 out of 11 streets, but when clicking to see the progress, it shows 11 streets completed. The city has 11 streets.
The nr. 1 for the city shows 11 out of 11 completed, but when clicking on the progress, it looks identical to the nr. 2 people (e.g. sew below, 0 in progress, 11 completed, yet elsewhere it shows 10 completed, yet 100%).
Other examples of cities with a similar behavior are shown below. All of these show N out of M streets completed, yet 100% completion. When clicking on the cities, M is indeed the total number of streets. But it then shows M completed and 0 in progress, so it’s unclear what’s the discrepancy.
Also, for the Hunts Points case, some nr. 2 ranked runners with 100% completion are in Hard Mode, so it doesn’t look like missed nodes. And overlaying the map of nr 1 and nr 2, both at 100% completion, doesn’t show any meaningful differences in streets and nodes covered.
