Leading observed checks

Open a matchup for a separate set-based damage estimate, or browse uploaded teams with both Pokémon.

Checks & Counters

Observed target KO or switch rate is upstream p: the fraction of relevant encounters where the target was knocked out or switched out. Standard error is upstream d. The conservative score is p − 4d. These ladder observations do not prove a set-specific counter.

How to read this table

Use encounter count and standard error to judge the sample. Damage estimates below use inferred sets and remain separate from the observed ladder metric.
