oh, I guess I'm just an idiot, jetpunk
Europe has 6 aswell but 45 countries, north america has 8/23 only 7/48 for asia, but south america actually wins with 6/12. Africa has 15 but out of a total of 54.
Interesting how 3 of the continents have 6 countries with a's and u's. (6,6,6,7,8,15 ok that's enough numbers for today, I'll spare you the actuall %)
