Points Above Averages. I think that rank %iles rely on luck and distribution (think Starcraft/WW) while PAAs are a more "standard" indicator. One point over average is just as good whether you ranked 35th or 57th...
Ah, I see. Yes, I can see how that might have some advantages over average %ile.
Though some matches will have lower averages than others - and much more importantly, some scoring systems will have lower averages than others. Thus giving a slight advantage to people who participated in contests with higher averages, as their points above average would be scaled up. Maybe point % above average? e.g. 3.5 points above average in a match where the average score was 35 points would be +10%?
You could also do average Z-scores (which also sounds cooler, everybody loves the letter Z!), though PAA or %PAA is more straightforward for people to understand. And penalties would make point distributions non-normal though so I don't now how valid that would be.
