adc
Karthus's WR vs enemy adc. Sort ↓ for Karthus's easiest matchups, ↑ for hardest (strongest counters).
Matchup score from Karthus's perspective. Z-score (mean 0, SD 1) of the weighted composite 0.70·z(delta) + 0.20·z(games) + 0.10·z(WR), pooled across this opponent role. Positive = favorable matchup, negative = hard matchup (strong counter). Same shape as the item synergy / counter pick / duo rankings.Karthus's Bayesian-smoothed win rate against this opponent.

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.
