This week vs last week
Genuinely weaker this week — win rate down about 0.4 points (52.7% → 52.3%). 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.

Buying it later goes with a lower win rate (2.7pp) — 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.
