Duo Report: the teammate scouting report for CS2

Field notes

The report model compares matches played with a teammate against filtered matches played without that teammate, while separating descriptive statistics from causal claims. The homepage specifies that rankings usually require at least 10 shared matches and that best-map results require five completed shared matches. It also distinguishes shared-team participation from intentional premade queueing, and excludes draws, remakes, and abandoned matches from win-rate calculations.
