Your Competitive Skill Rank (CSR) measures your performance against other players in Halo 4 Matchmaking War Games. You will have a CSR specific to each active playlist. Your best CSR is shown on your Player Card and Service Record, as well as Player Compare. Your Competitive Skill Rank can be seen on all screens of Halo Waypoint and measures your performance against other players in Halo 4 Matchmaking War Games. It is a number from 1 to 50 (higher is better) which will go up and down based on match outcomes. You will have a CSR specific to each active playlist, and your best CSR is shown on your Player Card and Service Record, as well as Player Compare.
