What it is
Look up a player, pick a match and get a grade from S to D in Laning, Combat, Economy, Vision and Objectives, with the gold curve and concrete things to improve.
The baseline isn’t a fixed table: it comes from your own opponents, so the grade measures real relative performance at any elo.

What I built
- A calibrated grade: 50 = your lobby’s median
- Gold curve, match history, champion browser and a read on the meta
- Heavy views loaded on demand (lazy + Suspense)
- State in the URL and keyboard shortcuts
The hard parts
01
A fair grade
With constant baselines, an Iron player got a D no matter what. Now the baseline comes from their own lobby.
