20 Tournaments. 12,172 Matches. Two Weekends.

Upsets are the heartbeat of competition. These are the matches where the lower-Jits fighter walked in, looked across at a name with a better record and more Jits, and won anyway. The Jits gap measures the distance between David and Goliath.

Full rebuild. Every rating recalculated from scratch.

Weight class awareness. The model now detects when a fighter moves up. Win at a higher weight? More credit. Lose up? Cushioned. Absolute and Open divisions too.

Boys are boys and girls are girls. In combined brackets (NAGA, AGF, Newbreed), girls sometimes fight boys. A girl who beats a boy gets properly rewarded. A girl who loses to a boy isn't penalized like she fought another girl.

White belt volume decay. White belt wins count for less the more you accumulate. A 35-0 white belt should've been promoted — the model now places them closer to the belt they're actually at. Grey belt and above: no decay.

Upset accountability. Losses to unproven opponents now cost more for elite fighters. The bigger the record, the bigger the price. David vs Goliath is real — and Goliath should feel it.

Progressive loss cap. One bad tournament can't destroy a career. The model caps how much you can lose from any single match.

Deep bracket credit. Fighting 4+ rounds to win gold in a 16-person bracket counts for more than a 4-person bracket. Silvers in deep brackets get credit for the wins it took to get there.
