USL Championship · Sunday, 20 September 2026. Final score 1–2 (half-time 1–1). Before kick-off we rated it 55% under 2.5 goals — the match finished with 3, so that call missed. That rating was frozen into a version-controlled ledger before the game and has not been touched since.

The league sets the starting point. USL Championship has produced over 2.5 goals in 50% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Rhode Island have 10 in 22 this season (4 of 11 at home), Miami FC 13 in 24 (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 48% and 52%.
Last season still counts, briefly. With 22 and 24 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 44% and 51%.
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 60%. 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 49%.
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 35%, from expected goals of 1.54 for Rhode Island and 0.56 for Miami FC. Folding in 30% of that view gives 45%.
Calibration. Tested against 97,729 past matches, our ratings below 55% have run consistently too pessimistic — a figure in the high 30s, for instance, has come in about four points higher. So ratings in that range are lifted part-way back, giving 46%.
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.
