How we calculate this
Games: ranked Solo/Duo and Flex games on the North America server from the patch shown. Remakes (games under 5 minutes) are excluded.
A game only counts when Kayn and Udyr played the same position on opposite teams, so roaming, lane swaps within a team or a champion merely being in the same game never count as this matchup.
The 95% range is a Wilson score interval. Confidence comes from how wide that range is: within ±3 points is very high, ±5 high, ±8 moderate, anything wider low. Below 20 games a matchup is not classified at all.
Expected win rate combines both champions’ win rates in this lane (same games and filters) with the log5 formula: E = A(1−B) / (A(1−B) + B(1−A)). Matchup effect = observed − expected.
"What changes" compares Kayn's choices in this matchup with the same champion's other games in the same lane, and lists a change only when it is at least 3 points and statistically significant (two-proportion z-test, |z| ≥ 2, 20+ games).
Results are not split by rank: the sample per rank is too small for honest per-rank matchup numbers.

Best Kayn Build vs Udyr
Usual Kayn build (Jungle)
70.8% win rate · 89 games
Against Udyr
Not enough matchup-specific build data: only 10 of 67 Kayn games against Udyr carried a complete build, which is too few to recommend an item path from. Use Kayn's standard build instead.
- Kayn usually completes Gustwalker Hatchling first, at 0.2 min (median of 38 games).
- Udyr usually completes Gustwalker Hatchling first, at 0.2 min (median of 67 games).
- Skill priority: Q > W > E — the same as usual.
Builds are ranked by the lower edge of their win rate range, not the raw win rate, so a build seen in a handful of wins never outranks a proven one.
