The result model puts Vanspor FK at 50%, the draw at 25% and İstanbulspor at 25%, from expected goals of 1.62 and 1.07.
The league sets the starting point. 1. Lig has produced over 2.5 goals in 53% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Vanspor FK have 1 in 2 this season (0 of 1 at home), İstanbulspor 2 in 2 (1 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 51% and 57%.
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 52% and 58%.
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 55%.
Head to head. These sides have met 2 times in three years, producing over 2.5 goals in 100%. 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 59%.
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 51%, from expected goals of 1.62 for Vanspor FK and 1.07 for İstanbulspor. Folding in 30% of that view gives 57%.
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.
