USL Championship · Saturday, 30 May 2026. Final score 2–0 (half-time 2–0). 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 result model puts Charleston Battery at 67%, the draw at 20% and Detroit City at 12%, from expected goals of 2.04 and 0.74.
The league sets the starting point. USL Championship has produced over 2.5 goals in 51% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Charleston Battery have 5 in 9 this season (3 of 4 at home), Detroit City 6 in 10 (3 of 5 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 54%.
Last season still counts, briefly. With 9 and 10 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 58% and 43%.
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 51%.
Head to head. These sides have met 7 times in three years, producing over 2.5 goals in 29%. 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 50%.
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 53%, from expected goals of 2.04 for Charleston Battery and 0.74 for Detroit City. Folding in 30% of that view gives 50%.
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 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.
