How is this data calculated?Raider.IO estimates cutoffs from recorded character scores and dungeon runs. Historical data may be revised as coverage improves.
Each qualifying character counts once; alts count separately. Faction, class, role and spec populations are calculated independently. Averaging faction cutoffs does not give the overall cutoff.
Top X% is the highest-scoring share of the selected population. Ties at the cutoff are included; rounding only affects displayed scores.
Historical coverage depends on retained runs and character data. Role and spec views use saved assignments; estimated specs are labeled. Missing data does not mean zero characters.
Compare populations at the same point in a season, using the same region and cohort. Raw scores are not directly comparable across seasons.
Ladder pressure bars count characters from just below the selected cutoff through the cutoff. Both ends of the displayed score range count, including ties. The same character can appear on multiple days.
