MLS · Sunday, 27 September 2026. Final score 3–3 (half-time 0–0). Before kick-off we rated it 56% over 2.5 goals — the match finished with 6, so that call landed. That rating was frozen into a version-controlled ledger before the game and has not been touched since.

The result model puts Austin at 31%, the draw at 27% and San Diego at 41%, from expected goals of 1.18 and 1.4.
The league sets the starting point. MLS has produced over 2.5 goals in 61% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Austin have 17 in 26 this season (5 of 12 at home), San Diego 17 in 26 (5 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 63% and 63%.
Last season still counts, briefly. With 26 and 26 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 60% and 62%.
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 61%.
Head to head. These sides have met 3 times in three years, producing over 2.5 goals in 67%. 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 61%.
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 48%, from expected goals of 1.18 for Austin and 1.4 for San Diego. Folding in 30% of that view gives 57%.
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.
