HOW IT WORKS

Computed, not voted.

Every FBS result feeds the same equation, recomputed from scratch each week. Nothing carries over from the week before.

See the full algorithm →

01

Calculate SDRs

SDR compares every FBS team by averaging the score of each game played this season. The more games that have been played, the better the data.

02

Break into quadrants

Using SDR, teams are sorted into quadrants. Q1 is anyone within reach of the best team in the country, Q2 is the next tier down, and Q3 covers the rest of the top 68.

03

Reward good wins

Teams earn points for wins against strong quadrants, without being punished too heavily for a loss to a good team.
