NWSL (W) · Monday, 14 September 2026. Final score 1–1 (half-time 1–0). Rebuilt from the season as it stood that morning, our rating would have been 51% for over 2.5 goals. This match is older than our frozen ratings ledger, which keeps 30 days, so that figure is a reconstruction from pre-match data rather than a number we published at the time — a distinction worth making, because only the frozen ones prove what we actually said beforehand.

The league sets the starting point. NWSL (W) has produced over 2.5 goals in 48% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Portland Thorns W have 13 in 23 this season (5 of 11 at home), Chicago Red Stars W 11 in 23 (6 of 12 away). Those records are pulled toward the league rate with the weight of about 24 matches — enough that two or three unusual games cannot swing a rating — giving 52% and 48%.
Last season still counts, briefly. With 23 and 23 games played this season, last season's rates are still blended in and fade out entirely by game 40 — the point at which our testing showed they stop adding accuracy. A single season is part luck, so each club's record is first pulled toward the league average by 34 games' weight. That moves the two figures to 48% and 50%.
The mix. Weighted 40% home side, 40% away side and 20% league — the split that beat every alternative across 30,582 matches of testing — that gives 48%.
Head to head. These sides have met 5 times in three years, producing over 2.5 goals in 0%. That nudges the number 5% of the way toward the head-to-head pattern — deliberately small, because fixtures change more than reputations do — landing on 46%.
Goal expectation. Separately a Poisson model built from attack and defence strength — using real expected-goals data where the league has it — puts this match at 61%, from expected goals of 2.67 for Portland Thorns W and 0.49 for Chicago Red Stars W. Folding in 30% of that view gives 51%.
This breakdown is generated from the same inputs the rating uses, so it cannot describe a calculation we did not perform. The full model is set out in the methodology.
