The Elo rating system provides a more accurate ranking than simple win rates:
- All models start at 1500 points
- Points are exchanged after each comparison based on the expected outcome
- Beating a stronger model earns more points than beating a weaker one
- The ± value shows the statistical confidence interval (95%)
