What data is available (and how)

• Name

• Leaderboard size

• Rank (absolute)

• CS Rating = score >> 15

• Data related to detailData:

  • Data is almost a ScoreLeaderboardData protobuf message. The first bytes is the header, indicating the protobuf length.
  • In matchentries, each tag corresponds to a certain field, see image below. Winrate is calculated from the win/draw/loss fields.

  

  • For RankWindowStats, it corresponds to the map spider graph indicating player's map "preferences" (maybe derived from wins). It's a 32 bit value, each 4 bits correspond to a map.
  • TimeAchieved is probably when the player gets into the leaderboard.

• Rank% (hidden from cs2 global LB) = Rank / data. It's an integer always capped between 1 and 99.
