J3 League · Saturday, 26 September 2026. Final score 4–3 (half-time 1–1). Rebuilt from the season as it stood that morning, our rating would have been 55% for over 2.5 goals. This game was not captured by our pre-kick-off freeze, 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 Fukushima United at 52%, the draw at 23% and Parceiro Nagano at 25%, from expected goals of 1.95 and 1.31.
The league sets the starting point. J3 League has produced over 2.5 goals in 49% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Fukushima United have 7 in 7 this season (3 of 3 at home), Parceiro Nagano 2 in 7 (1 of 3 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 61% and 44%.
Last season still counts, briefly. With 7 and 7 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 44%.
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 4 times in three years, producing over 2.5 goals in 50%. 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 51%.
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 63%, from expected goals of 1.95 for Fukushima United and 1.31 for Parceiro Nagano. Folding in 30% of that view gives 54%.
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 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.
