The result model puts Matsumoto Yamaga at 29%, the draw at 27% and Osaka at 44%, from expected goals of 1.06 and 1.37.
The league sets the starting point. J3 League has produced over 2.5 goals in 48% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Matsumoto Yamaga have 2 in 4 this season (2 of 2 at home), Osaka 2 in 4 (0 of 2 away). Those records are pulled toward the league rate with the weight of about 32 matches — enough that two or three unusual games cannot swing a rating — giving 51% and 45%.
Last season still counts, briefly. With 4 and 4 games played this season, last season's rates are still blended in and fade out entirely by game 14 — the point at which our testing showed they stop adding accuracy. That moves the two figures to 45% and 45%.
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 45%.
Head to head. These sides have met 4 times in three years, producing over 2.5 goals in 0%. That nudges the number 10% of the way toward the head-to-head pattern — deliberately small, because fixtures change more than reputations do — landing on 41%.
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 44%, from expected goals of 1.06 for Matsumoto Yamaga and 1.37 for Osaka. Folding in 30% of that view gives 42%.
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.
