MLS · Sunday, 17 May 2026. Final score 1–1 (half-time 0–0). Rebuilt from the season as it stood that morning, our rating would have been 55% 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 result model puts DC United at 27%, the draw at 27% and St. Louis City at 46%, from expected goals of 1.06 and 1.45.
The league sets the starting point. MLS has produced over 2.5 goals in 60% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. DC United have 7 in 13 this season (4 of 5 at home), St. Louis City 4 in 12 (1 of 7 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 58% and 51%.
Last season still counts, briefly. With 13 and 12 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 57% and 60%.
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 59%.
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 46%, from expected goals of 1.06 for DC United and 1.45 for St. Louis City. Folding in 30% of that view gives 55%.
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.
