The result model puts Charleston Battery at 84%, the draw at 11% and Monterey Bay at 5%, from expected goals of 3 and 0.62.
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. Charleston Battery have 15 in 24 this season (8 of 11 at home), Monterey Bay 12 in 24 (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 56% and 50%.
Last season still counts, briefly. With 24 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 57% 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 53%.
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 70%, from expected goals of 3 for Charleston Battery and 0.62 for Monterey Bay. Folding in 30% of that view gives 58%.
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.
