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).
