The result model puts Iwaki at 49%, the draw at 27% and Albirex Niigata at 24%, from expected goals of 1.42 and 0.9.
The league sets the starting point. J2 League has produced over 2.5 goals in 45% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Iwaki have 2 in 2 this season (1 of 1 at home), Albirex Niigata 1 in 2 (0 of 1 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 49% and 44%.
Last season still counts, briefly. With 2 and 2 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 43% and 49%.
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 46%.
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 41%, from expected goals of 1.42 for Iwaki and 0.9 for Albirex Niigata. Folding in 30% of that view gives 44%.
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.
