I haven't done the math, and I am not sure I will, but the percentage system bothers me a bit. I wonder whether a "% differencial" system would be substantially fairer.
It is basically a point-differential system, but with every game being worthy 100 points. Those who know math around here, could you tell me whether this would improve the current system or it is just the same thing with other clothes?

TeamA%points + TeamB%points = 100.
Team%points = (TeamPoints*100)/(TotalPointsScored)
%Diff. = Team%points - Opponent%points

Then, it is just a matter of adding up the %Differential for every game throughout the season.
For instance, we have beaten Melbourne by 75-65, in a total of 140 points scored.
(75*100)/140= 53.57
(65*100)/140= 46.43
Port's %Diff. would have been +7.14
Melbourne's, -7.14
