With some spare time, I sketched the leaderboards for the last four challenges, ordered by country (the ones currently specified on each user's profile, where present) and continent, to have a better perspective about it. Most are indeed pretty close (except for the first one):

It's very interesting how close things are when things are divided by continent, and given the wide spread by individual countries, it may be prudent for organizational purposes to focus on that rather than doing individual countries. You'll likely have a lot on your plate come December, I have a feeling these newer stats will likely draw in a much bigger collective total of virgins compared to this one.

Oh yeah, I forgot to say that what you did there looked very cool, Burning! And I'm very happy to bring some balance to team Asia (and Oceania) who seem to be growing in strength.

Heh, the whole thing's actually been easier, and faster, than it would seem.
