A-League · Friday, 16 October 2026 · 10:00. Final score 0–0 (half-time 0–0). Before kick-off we rated it 59% over 2.5 goals — the match finished with 0, so that call missed. That rating was frozen into a version-controlled ledger before the game and has not been touched since.

| Market | Price | Implied | Our rating | Edge |
|---|---|---|---|---|
| Over 2.5 goals | 1.70 | 55% | 50% | -5% |

Implied percentages have the bookmaker's margin removed, so they add to 100 and can be compared with our rating directly. Edge is simply the gap between the two. A positive edge means our model thinks the outcome is likelier than the price suggests — it is not a tip, and a high probability with a negative edge is a poor bet however safe it looks. Prices are a pre-match snapshot from a single bookmaker and move constantly.
Match odds: Sydney 2.25, draw 3.70, Western Sydney Wanderers 2.90.
The league sets the starting point. A-League has produced over 2.5 goals in 56% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Sydney have 0 in 0 this season, Western Sydney Wanderers 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 56% and 56%.
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 47% and 52%.
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 51%.
Head to head. These sides have met 9 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 52%.
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 1.67 for Sydney and 1.03 for Western Sydney Wanderers. Folding in 30% of that view gives 51%.
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 49%.
Calibration. Tested against 97,729 past matches, our ratings below 55% have run consistently too pessimistic — a figure in the high 30s, for instance, has come in about four points higher. So ratings in that range are lifted part-way back, giving 50%.
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.
