How this rating change was computed

Glicko-2 doesn’t reward record — it rewards surprise. Winning a match the system expected you to win is worth almost nothing. Losing one is expensive. Losing to someone rated below you costs the most. The Planetary tier multiplier (1.0×) amplifies every gain and every loss. Top-cut rounds add more on top (Quarterfinals +0.15, Semifinals +0.25, Finals +0.35).

Phase Record Raw Glicko-2 Multiplier Applied Running
Swiss · 6 matches 5-1 +38.3 1.0× +38.3 1606
Quarterfinals · 1 match 0-1 -9.9 1.15× -11.4 1594
Total 5-2-1 +28.0 1595

Phase numbers use each opponent’s pre-tournament rating (the one shown on the leaderboard). The engine uses the opponent’s rating at the moment of the match — which for top-cut rounds includes their own Swiss performance — so the phase contributions above are approximate for Quarterfinals, Semifinals, and Finals. The Total is the engine’s actual output.

Per-match multipliers reflect what the engine applied at the time this snapshot was recorded. The Effective Multiplier above is a delta-weighted average across all phases — Finals matches swing the headline more than Swiss rounds when they produced bigger rating changes. How it works.
