Player Ratings
Player ratings on esport.is are derived from PandaScore's performance score, which combines kill/death ratio, win rate, and tournament-level performance weighted by opponent strength. Ratings are on a 0–2 scale where 1.0 represents average performance. A rating above 1.15 indicates an elite performer. These are updated after each match.
Team Rankings
Global rankings use PandaScore's Elo-based rating system, which factors in recent match results, tournament tier (Major > LAN > Online), opponent rank at time of match, and series format (Bo3/Bo5 weighted higher). CS2 rankings additionally surface Valve's official regional standings separately.
Live Match Scores
Live match scores are polled from the PandaScore live data endpoint every 30 seconds during active matches. Map scores, round counts, and series state are updated in real-time. Our pages re-validate every 30 seconds for live match data.
Transfer Data
Transfer and roster move data is sourced from official team announcements, verified esports news outlets and community submissions. Entries are manually reviewed before publication. Transfers are community-reported and may not represent all moves — always verify with official team channels.
Patch Notes
Patch versions and dates are sourced from official developer patch note pages and manually verified by the esport.is editorial team. The patch data refreshes daily. Links always point to the official developer patch notes page.
Prize Pool Data
Tournament prize pools are sourced from official tournament operator announcements and PandaScore event data. Amounts shown are gross prize pools in USD unless otherwise specified.
