J3 League · Saturday, 3 October 2026. Final score 1–0 (half-time 0–0). Rebuilt from the season as it stood that morning, our rating would have been 43% 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 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. Sagamihara have 6 in 8 this season (2 of 4 at home), Osaka 5 in 8 (1 of 4 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 55% and 52%.
Last season still counts, briefly. With 8 and 8 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 45% and 48%.
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 47%.
Head to head. These sides have met 5 times in three years, producing over 2.5 goals in 40%. 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 47%.
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 30%, from expected goals of 0.69 for Sagamihara and 1.2 for Osaka. Folding in 30% of that view gives 41%.
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 43%.
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.
