This week vs last week
Genuinely stronger this week — win rate up about 0.7 points (49.7% → 50.3%). 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.
Win rate by when it was bought
- Before 10 min52.0% (51.8–52.2, 197,941)
- 10–20 min50.9% (50.7–51.0, 707,889)
- After 20 min49.1% (49.0–49.3, 564,370)
Buying it later goes with a lower win rate (2.9pp) — a real gap, but remember late buys usually mean you were already ahead.
Read this before trusting the number
An item's win rate is correlational. Expensive late-game items post high win rates largely because you only complete them when your team is already ahead — not because the item is what won the game. Use it to see what the strong builds tend to include, not as a causal "buy this to win" ranking.
Win rate is the share of matches won when this item was bought, 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.
