Synergy score from Jarvan IV's perspective. Per-result-set z-score (mean 0, SD 1) of the weighted composite 0.70·z(delta) + 0.20·z(games) + 0.10·z(WR). Positive = ally helps Jarvan IV, negative = ally drags Jarvan IV down. Same shape as the item synergy / counter pick / duo rankings + matchup tables.Jarvan IV's Bayesian-smoothed win rate when paired with this ally.Bidirectional synergy delta: avg of Jarvan IV's gain over their baseline and the ally's gain over theirs.

Worst MatchupⓘWorst lane matchup WR minus this champion's own baseline WR, both Bayesian-smoothed. Tail complement to Matchup Spread — captures champions punished by a small number of extremely spiky lanes that MAD averages out. Closer to 0 = no truly bad lanes (safer blind pick). Min 30 games per opponent, ≥5 well-sampled opponents.
-4.4%
Best MatchupⓘBest lane matchup WR minus this champion's own baseline WR, both Bayesian-smoothed. Higher = stronger counter-pick power against the right opponent. Min 30 games per opponent, ≥5 well-sampled opponents.
