How the numbers work
All-play is a team's record if it had played every other team every week. It strips out schedule luck, so it's the best single measure of how good a team really was. Luck is actual wins minus the wins the all-play rate predicts. Power rankings blend all-play win rate (50%), actual win rate (30%) and the last three weeks of scoring (20%).
A week only counts once all of its games are final, so in-progress scores never skew the records.
Who runs it
