@Tru Ninja, while your numbers ring true on draws, your explanation of the higher percentage is flawed.
Let's take your same three sample games and remove france from game 1, making it a 2-way draw.
game 1: drawn by austria, italy
game 2: drawn by russia, france, turkey
game 3 drawn by england, germany, russia
You logic of three games = 300% should still apply, but we'll show why it doesn't:
Austria draws 1/3 of the time
Italy draws 1/3 of the time
France, who used to draw 2/3 of the time now draws 1/3 of the time
Turkey, England, and Germany still draw 1/3 of the time each and Russia still draws 2/3 of the time.
That adds up to 8/3 or 266.7%. Where did the other 33.3% go?
I'll explain.
The real logic is that the total percent is based on the total number of a given type of draw/total number of drawn games then multiplied by the number of players in that type of draw (2 for 2-ways, 3 for 3-ways). So, in this example 1/3 of the games are 2-way draws and 2/3rds are three way draws. The total percentage is then 2*33.3333 (the 2 times the percent of 2-way draws) + 3*66.6667 (3 * the percent of 3-way draws) which equals 266.7%.
