I have numerous times where I have completed / made progress on a street, it shows up on my LifeMap, but does not show up as progress or completed in the activity.
Here’s a recent example where on Aug 28 I did a few blocks of Berger Alley, as shown on my LifeMap but the progress is not on my activity:
Each street has a show/go button. If you click the Go button, you’ll be taken to its page where it will show you this stat.
In the case of your screenshot, each of the intersections were likely completed by one of the many other activities … and together, this resulted in Berger Alley being marked as completed.
So, even though you didn’t run between the nodes in the intersections, each node was marked as complete and therefore the entire street was marked as complete.
That’s a bit of a current limitation in the way that I built the system to process activities against node data … Grid cities like we both live in result in cross-streets being marked as complete prematurely.
