This week vs last week
Basically unchanged — win rate wobbled up about 0.0 points (49.3% → 49.3%), but that's inside the normal week-to-week randomness, not a real move.
p = 0.2847 — the odds a swing this big is just luck — too high to trust as a real change across all the heroes we test each week.
Win rate by when it was bought
- Before 10 min49.6% (49.5–49.6, 2,499,747)
- 10–20 min46.7% (46.4–47.0, 138,377)
- After 20 min44.8% (44.3–45.2, 49,314)
Buying it later goes with a lower win rate (4.8pp) — 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.
