Six criteria, every performance.
Every performance is judged on six criteria, each scored 0–100 and weighted. The weights shift by style — traditional events reward foundation, open events reward difficulty.
Judged for the style.
Traditional events prize foundation — clean technique, power, and a rooted base carry the most weight.
Open events open the door to difficulty and composition, rewarding what a competitor dares to attempt.
From judges to a final score.
Rank and rating aren't the same.
Your belt tier
Set by your school — beginner, intermediate, advanced. The tournament never changes it. Rank is how you're grouped for a fair division.
How your rating moves.
Every competitor starts at 50. After each round, your rating adjusts by how you placed against competitors of your same rank. The system expects the higher-rated competitor to come out ahead — so beating a stronger one moves you up more, and an upset is rewarded.
Your first three rounds move faster, so you find your level quickly; after that, steadier steps. Ratings always stay between 0 and 100, and only ever move you against same-rank competitors.
expected = 1 / (1 + 10 ^ ((opponent − you) / 40))
# your change, summed over opponents
change = (K / opponents) × Σ (result − expected)
# result = 1 win · 0 loss · ½ tie
# K = 8 for your first 3 rounds, then 4
What carries the season.
Standings come from your best five of nine rounds, by placement — computed independently of your rating. They're what carry you toward the semi-finals and Grand Finale.
The weights and rating settings shown here are the current season's configuration, and may be tuned between seasons to keep competition fair. Scores are computed on our servers from the judges' inputs — never on a competitor's device.
