Methodology

The pre-match model uses team-level signals only: Elo ratings, season win rate, H2H record, and recent form — no champion data, frozen at prediction time. Hermes (the at-draft agent) adds seven signals including champion win rates and duo synergies. Brier score measures probabilistic accuracy: 0 = perfect, 1 = maximally wrong, 0.25 = equivalent to a 50/50 coin flip. Lower is better. Predictions are pre-registered — they cannot be edited after creation.
