How the ranking works

ISL Rating 2.0

One number for how well a player actually played — not just how many kills they got.

• KASTThe share of rounds where you did something that mattered: a kill, an assist, you survived, or a teammate traded your death.
• Kills and deathsHow much you frag, set against how often you go down.
• ImpactExtra credit for kills and assists that actually swing rounds, rather than padding a scoreline.
• ADRAverage damage per round — the work you do even when someone else takes the kill.

Everything is per round. A long 30-round map and a quick 16-round one count the same, so nobody gains from matches simply running long.

Around 1.00 is a solid average. 1.15+ is a strong season.
