| Market | Yes | No | Our call |
|---|---|---|---|
| Over 2.5 goals | 58% | 42% | Over |
| Over 3.5 goals | 36% | 64% | no pick |
| Both teams to score | 56% | 44% | Yes |
The result model puts Brisbane Roar FC W at 50%, the draw at 25% and Sydney FC W at 25%, from expected goals of 1.72 and 1.16.
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. Brisbane Roar FC W have 1 in 1 this season (1 of 1 at home), Sydney FC W 1 in 1. 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 60% and 60%.
Last season still counts, briefly. With 1 and 1 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 64% and 55%.
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 59%.
Head to head. These sides have met 5 times in three years, producing over 2.5 goals in 60%. 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 60%.
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 55%, from expected goals of 1.72 for Brisbane Roar FC W and 1.16 for Sydney FC W. Folding in 30% of that view gives 58%.
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.
| Team | Games | O2.5 | O3.5 | BTTS |

Our numbers give this match a 67% chance of at least one goal before half-time and 45% of two or more. The A-League (W) rates are 66% and 44%. After the break: 79% for a goal and 44% for two or more (league 79% and 44%). Brisbane Roar FC W's last 50 games had a first-half goal 78% of the time and a second-half goal 90%; Sydney FC W's last 50, 60% and 70%. Team form says less about a single half than about a full match, so these numbers stay close to the league's.
Every match ranked the same way: first half goals today · second half goals today · tomorrow.
