Updated the tables at the first page.
I don't agree with including Tsukuba at all. It's too small IMO, but it's always welcome for a vote.
Anyway, here is i what i have in mind.
1 Suzuka
2 Fuji
3 Datona Road
4 Laguna Seca
5 Indianapolis Road
Special Event: 9 Nurburgring 24 hours (Time Change 200km mini-enduro)

6 Circuit de la Sarthe (Time Change 200km mini-enduro)
7 Moza
8 Monaco
9 Fuji
10 Suzuka (200km mini-enduro)
From Japan > to the Americas > to Europe > and back to Japan to finish it off.
