ADR

(transport, international law) The Agreement on the International Carriage of Perishable Foodstuffs and on the Special Equipment to be used for such Carriage (ATP).

A round, game, or performance where a player's Average Damage per Round comes in embarrassingly low — the kind of output that reveals they spent most of the game hiding, missing shots, or avoiding fights rather than contributing to their team's pressure. An adr fail is often discovered post-match when the stats come up and someone scrolls to the bottom to find a number that contradicts whatever narrative the player was spinning about their session. No highlights cover for an adr fail.

The progression of a player's Average Damage per Round output over the course of a competitive season, tournament run, or career — the narrative of how their damage contribution has evolved. An adr arc might describe a rookie who was fragile in duels early on gradually becoming a consistent damage dealer, or an experienced player whose numbers are declining. In data-heavy esports communities, tracking someone's adr arc is a way of telling their competitive story through numbers rather than highlights.
