The result model puts Sydney FC W at 41%, the draw at 28% and Adelaide United W at 31%, from expected goals of 1.31 and 1.1.
The league sets the starting point. A-League (W) has produced over 2.5 goals in 58% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Sydney FC W have 0 in 0 this season, Adelaide United W 0 in 0. Those records are pulled toward the league rate with the weight of about 24 matches — enough that two or three unusual games cannot swing a rating — giving 58% and 58%.
Last season still counts, briefly. With 0 and 0 games played this season, last season's rates are still blended in and fade out entirely by game 40 — the point at which our testing showed they stop adding accuracy. A single season is part luck, so each club's record is first pulled toward the league average by 34 games' weight. That moves the two figures to 55% 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 57%.
Head to head. These sides have met 6 times in three years, producing over 2.5 goals in 67%. That nudges the number 5% of the way toward the head-to-head pattern — deliberately small, because fixtures change more than reputations do — landing on 57%.
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 43%, from expected goals of 1.31 for Sydney FC W and 1.1 for Adelaide United W. Folding in 30% of that view gives 53%.
Season opener. One of these sides has not played a league game yet. Openers run about 2.5 points under their league's norm, measured across 2,727 of them, so the rating is docked to 51%.
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.
