i recalculated it
it "could" work - my 2 preferred systems :P
sys1) 1 team germany, team GB, team benelux, team USA and team <Rest>
league system - maybe 2 games against each team
sys2) 2 german teams, team benelux, team GB, team USA and team <Rest>
2 divisions á 3 teams - #1's and #2's move on ...
