If it's known before anyone kicks a ball, no problem. It could happen (and after all, rankings for national football teams are weighted by continent), but if all the teams know about it, what's the problem? They all know what they have to do. It's not like the rules were changed halfway through the event to benefit one participant. They were set months back. Personally I think the double-points final race is codswallop, but it's been there forever. Everyone knows about it and plans accordingly.
