This week vs last week
Genuinely stronger this week — win rate up about 1.2 points (47.3% → 48.5%). This is a real move, not random weekly noise.
p < 0.000001 — the odds a swing this big is just luck — low enough to clear our bar for calling a change real.

Strong against
Struggles against
Only matchups whose win rate is far enough off an even 50% to be real over 43 tested opponents (Bonferroni-corrected). A big edge on few games is a wide error bar, not a counter — those stay hidden.
Teammates that matter · real and ≥2 points off even
Best paired with
Duo win rate on the same team, shown only where it's significantly off 50% over 43 tested partners (Bonferroni-corrected). Correlational, not causal — good players may simply favour the pairing.

Win rate is over a rolling 7-day window; the trend compares it to the 7 days before, with a Bonferroni-corrected two-proportion z-test so a normal weekly wobble isn't reported as a shift. Data from deadlock-api.com, refreshed hourly.
