| Market | Yes | No | Our call |
|---|---|---|---|
| Over 2.5 goals | 55% | 45% | Over |
| Over 3.5 goals | 30% | 70% | no pick |

The result model puts Central Coast Mariners W at 50%, the draw at 25% and Adelaide United W at 25%, from expected goals of 1.63 and 1.07.
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. Central Coast Mariners W have 1 in 1 this season, Adelaide United W 1 in 1 (1 of 1 away). 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 59% 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 58%.
Head to head. These sides have met 5 times in three years, producing over 2.5 goals in 20%. 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 56%.
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 1.63 for Central Coast Mariners W and 1.07 for Adelaide United W. Folding in 30% of that view gives 55%.
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 |

| Adelaide United W | 1 | 100% | 100% | 100% |
Our numbers give this match a 66% chance of at least one goal before half-time and 42% of two or more. The A-League (W) rates are 66% and 44%. After the break: 80% for a goal and 42% for two or more (league 79% and 44%). Central Coast Mariners W's last 50 games had a first-half goal 54% of the time and a second-half goal 80%; Adelaide United W's last 50, 78% and 82%. A goal in both halves: 55% (league 54%). Highest-scoring half: second 43%, first 31%, level 26% — close to the league's usual split, because team form says little about which half is busier. 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 · goal in both halves today · tomorrow.
