yep that's it....
ranked you get reputation points everytime you win.. it's 10% of the total anount of the oponents points.
And loose points if you loose a race 3 place 5% of you points and 4th place 10% of your points, 2nd place play even...
1on1 is 10% of his points if you win, loose 10% of you points if you loose
you will start with 100 points and it can't get lower, so loose the first race you play even...
BTW don't challenge HIGH rep racers... aslong as your rep is low... they ignore you and some fools are even irritated by it...
I have a rep of 200.000 now in circuit and 254.000 in Drift, my world rank is around the 2000th place...
UNranked games are just about racing not more not less...
