The National Circuit ELO Rating.
Every player on the National Circuit leaderboard carries a Rating — a single number that estimates true skill based on
real match results, not just wins and losses on paper.
Built on TrueSkill™

Our system is built on TrueSkill™, an open source ranking system developed for ranked competitive matchmaking on Xbox Live.
Unlike a traditional win/loss ladder, TrueSkill tracks two things for every player:
– Skill — our best estimate of how good you are.
– Uncertainty — how confident we are in that estimate.
When you first appear, your rating is uncertain and moves quickly. As you play more matches, the system becomes more confident and your rating stabilizes. This is why a strong performance early on can swing your number more than the same performance after dozens of matches.
It understands who you beat.
Beating a top-ranked team is worth far more than beating an unseeded one. Because ratings are calculated across the
whole field at once, every result is weighed against the strength of the opponents involved — so the leaderboard
rewards quality of competition, not just quantity of wins.
It rewards how you win and how you play.
Two things beyond the final result shape your rating:
– Margin of victory — a decisive win counts for more than a narrow one, so dominant performances are reflected in the
standings.
– Individual performance — along with winning the game, the system also accounts for individual performance. Kills, proportionate to the entire lobby, increases skill rating. And deaths hinder your rating. So getting a lot of kills is less impactful on the rating when you have equally as many deaths.
