Source line
Map Rating evaluates how your proficiency on a given map changes over time with a 0 to 500 rating and C to S letter grade.
- Your rating is based on four primary stats: Overall Win Rate, Attacker Win Rate, Defender Win Rate, and Performance Score.
- Recent matches contribute more to your rating and stats than older matches.
- Other players are not able to see information about your Map Rating.
- Everyone starts fresh with the Map Rating launch - historical match data will not count.
