Kai'Sa Jungle gets worse as the elo rises. 43.7% across Silver and above, but 40.8% once you look at Emerald and up. Sites that only sample high elo will show you the second number. Both are real; which one applies depends on the games you are actually playing.

Where these numbers come from

We read finished ranked solo queue games directly from Riot and keep a running tally. Nothing is copied from another site.

Matchups compare Kai'Sa against the enemy champion in the same lane, counting only games where both were actually there. The counters list pulls each matchup toward Kai'Sa's own win rate by 180 games' worth of it, then keeps the ones still under 50%. A matchup seen thirty times barely moves off the champion's average, and one seen a thousand times keeps close to its own number.

Every number here is followed by the games behind it, because that's what tells you how much to trust it. A win rate over a few hundred games is worth reading. The same number over thirty is mostly luck.

Recent games show what was built and who won. They never show who played. Rank is grouped (Master and up is one band), game length is rounded to five minutes, and there's no region or date on a card.

Every ranked game we read this patch adds its finished items here, boots aside. Items are listed in the order they sit in the inventory, which isn't always the order they were bought: a finished item takes the slot its first part was in.

Compare a win rate only with the other picks in its own slot. A fifth item mostly shows up in long games, and those skew toward the team that was already ahead, so late slots run hot whatever sits in them. A row needs 30 games before it shows up at all.

Built from real ranked games this patch. We keep the running totals, never the games themselves.
