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.
-4.5%
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.
