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 +0.05,
Semifinals +0.10,
Finals +0.15).

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.
