It works, as the rules say. A sudden death match.
My point is that the definition of exactly what a draw means isn't quite clear. Maybe just tweak the working so that it says something like "If two people have the same number of points, we go to a sudden victory match"?
It's all there if you literally read the point system, but it's a bit different from how a lot of scoring systems are done, so a bit of clarification wouldn't hurt.
Also, by sudden victory does it mean 1 game match?
