As of now, 111K pictures have been transferred according to your tool.
According to OSC profile page, only 36K pictures were counted and honored with “points”. All uploaded tracks of the 111K pictures are shown in the user profile overview, but not all were counted or honored. System overload? Also corresponding tracks for each upload are not shown in the general map for a lot of streets.
What sometimes happens: if my route went e.g. through a public park not open for cars, the OSC line string in the map is shown on the next street nearby if present. If you click on this line string itself, no details section is opened at the page bottom. But if you click on the invisible track (which exact position only the uploader knows), the details are shown.
This looks like OSC is a little too street focused and denies to show any other path - at least this is my current understanding.
Yes, at least it is a backup.
