  That is the canonical source for documentation.  We've spent a fair bit of time updating that site to be current and correct.  It's good to see that it's helpful.

  That being said, the statistics aren't always perfect.  I took a quick look, and there were cases where the stats weren't updated.

  I've pushed a change which should help.

  Issues.  See above.

  Hmm... I'm not sure.  I'll take a look.
