at the end of the 4 courses, whoever you beat, you get 1 win.
and whoever you lose to, you get 1 loss.
so if you're first, in a 4 person game, you will get 3 wins.
and if you get last, in a 4 person game, you will get 3 losses.
second place, 2 wins and a loss.
third place, 1 win and 2 losses.
at least, i think that's how it works.
