Competition
Delve's boards: everyone plays the same dungeon each day, so every run is on one scale.
More about this
First run leads: each champion's free run of the day, one try each. Best of the day counts retries, This week the best five days, All time the record and Skill the last 20 days. A bracket with fewer than 30 first runs that day shares its board with its neighbours. No prizes.
Free runs compared within their cohort, so Skill measures play rather than level.
Delve boards
Each champion's free run is compared only with its cohort on the same day's dungeon.
The rating is the mean of its percentiles over its last 20 days played, and stays provisional until it has 10.
