Each offense and defense stat becomes a league percentile from 0 to 100, and teams with the same value share the middle percentile. A team missing one offense or defense stat has that unit left unscored, rather than giving the missing weight to the other stats. Overall needs only finished games, so a team that has not played is not scored.

Each score is worked out first. Then the lowest team is set to 0, the highest to 100, and the rest are spaced in proportion between them. This never changes ranks or ties: equal scores are ordered by win percentage, then team name. Filters never change scores or ranks. The numbers in a team's scorecard breakdown stay on their own scales, so they add up to Overall before it is placed on the 0 to 100 range.

Score labels show whole numbers where they can. When two scores would share a whole number, one keeps a decimal so the order stays clear. Equal scores share a label. Only the labels are rounded, never the scores, meters or ranks.

Points include defensive and special-teams scores. Team passer rating is the traditional passer rating, not ESPN's QBR. Net yards per play counts passing yards after sacks plus rushing yards, over every offensive play. Offense and defense compare plain season numbers, and only Overall adjusts for the opponents played. Analyst opinions play no part.

Scoring strength starts from each team's average points margin and accounts for every opponent's strength in one league-wide calculation. Teams with few games are pulled toward average, which keeps early-season numbers steady. Each point of adjusted margin is worth 3 points on a strength scale centered on 50 and kept between 0 and 100. A team's scorecard shows these inputs and both halves of Overall.

The even split between results and scoring margin, and the 3 points per point of margin, are descriptive choices, not predictions. There is no home-field or injury adjustment, and the scores are not built or tested to forecast games.
