How Summer League Points/Rating Works

Players start with a rating based on their level (e.g., 3.5 = 3500, 4.0 = 4000). After each match, ratings are updated using an Elo system.

Formula:

New Rating=Old Rating+K×(Actual−Expected)

  • Actual = 1 for a win, 0 for a loss

  • Expected = probability of winning based on rating difference

  • K-factor = controls how much ratings move

K-Factor:

  • Weeks 1–8: K = 48 (higher movement to adjust rankings quickly)

  • Weeks 9–18: K = 32 (lower movement for stability)

    These may be adjusted before league starts depending on skill gap

How it works in practice:

  • Beating a higher-rated player results in a larger point gain

  • Beating a lower-rated player results in a small gain

  • Losing to a higher-rated player results in a small loss

  • Losing to a lower-rated player results in a larger loss

Each match counts as a single result (win or loss), and only completed matches are included. Rankings are updated weekly based on current ratings.
