Reliability ranks observed matchups; KO rate is how often the checker knocked out or forced out the target. “Checker faints” reports the checker's own observed death rate. Categories use matchup reliability plus offensive and defensive base stats.
How to read this table
Use encounter count to judge sample size. A high-reliability check with a modest KO rate can still be useful when it consistently forces switches or limits the target.
