|---|---|---|---|
| Elo | Good | Fast | 1v1 games |
| TrueSkill | Excellent | Medium | Team games |
| Glicko-2 | Excellent | Slow | Chess, turn-based |

| Error | Root Cause | Solution |
|---|---|---|
| Long queue times | Too strict matching | Increase expansion rate |
| Unbalanced matches | Fast expansion | Tune quality threshold |
| Rating inflation | No decay | Add seasonal reset |
