🔍 How BJJMetrics Elo Rankings Work

Elo is a rating system originally developed to rank chess players, and it's now used across many sports and games.

It calculates a competitor's skill based on match results and the strength of their opponents, using a probabilistic model. The core idea:

At BJJMetrics, we've adapted this system for BJJ, with a few key enhancements:

Bigger Upsets = Bigger Gains
Winning against a higher-rated fighter earns you more points.
Expected Wins = Small Gains
Beating someone below your level gives only a small rating boost.
Event Bonuses
Winning at Worlds or Grand Slams adds extra points to reflect the event's prestige.
New Fighters Rise Fast
Everyone starts at 1000 and can climb quickly by consistently winning — especially against tough opponents.
Compare Across Belts and Divisions
Our Elo scores reflect overall competitive strength, making it possible to compare athletes across divisions and belts.

ELO Calculation Formula
New ELO = Old ELO + K-Factor × (Actual Score - Expected Score) + Bonus
Probability of Victory = 1 / (1 + 10^((Opponent ELO - Your ELO) / 400)) × 100%
Expected Score = Probability of Victory / 100 | K-Factor = 32
Regular Bonus = 0 | Grand Slam Bonus = +30 | Worlds Bonus = +50
