Q: Why do the graphs end 2 days in the past and not today?<p>A: Relays and bridges report some of the data in 24-hour intervals which may end at any time of the day.  And after such an interval is over relays and bridges might take another 18 hours to report the data.  We cut off the last two days from the graphs, because we want to avoid that the last data point in a graph indicates a recent trend change which is in fact just an artifact of the algorithm.<p>Q: But I noticed that the last data point went up&#x2F;down a bit since I last looked a few hours ago.  Why is that?<p>A: The reason is that we publish user numbers once we&#x27;re confident enough that they won&#x27;t change significantly anymore.  But it&#x27;s always possible that a directory reports data a few hours after we were confident enough, but which then slightly changed the graph.<p>from the Q&amp;A <a href="https:&#x2F;&#x2F;gitweb.torproject.org&#x2F;metrics-web.git&#x2F;tree&#x2F;doc&#x2F;users-q-and-a.txt" rel="nofollow">https:&#x2F;&#x2F;gitweb.torproject.org&#x2F;metrics-web.git&#x2F;tree&#x2F;doc&#x2F;users...</a>
