Our ratings for this match

The result model puts Omiya Ardija at 44%, the draw at 29% and Shonan Bellmare at 27%, from expected goals of 1.21 and 0.89.

How we got this number

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. Omiya Ardija have 1 in 2 this season (0 of 1 at home), Shonan Bellmare 0 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 44% and 41%.

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 55% and 46%.

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 49%.

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 35%, from expected goals of 1.21 for Omiya Ardija and 0.89 for Shonan Bellmare. Folding in 30% of that view gives 45%.

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.
