The result model puts Avellino at 16%, the draw at 23% and Arezzo at 61%, from expected goals of 0.78 and 1.79.
The league sets the starting point. Serie B has produced over 2.5 goals in 47% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Avellino have 18 in 39 this season (10 of 19 at home), Arezzo 18 in 42 (9 of 20 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 48% 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 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 47%, from expected goals of 0.78 for Avellino and 1.79 for Arezzo. Folding in 30% of that view gives 47%.
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.
