Süper Lig · Sunday, 18 October 2026 · 14:00. Final score 1–2 (half-time 0–1). Before kick-off we rated it 56% under 2.5 goals — the match finished with 3, so that call missed. That rating was frozen into a version-controlled ledger before the game and has not been touched since.

| Over 2.5 goals | 2.00 | 47% | 44% | -3% |

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: Kocaelispor 2.75, draw 3.25, Göztepe 2.45.
The league sets the starting point. Süper Lig has produced over 2.5 goals in 54% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Kocaelispor have 2 in 7 this season (0 of 3 at home), Göztepe 6 in 7 (4 of 4 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 48% and 61%.
Last season still counts, briefly. With 7 and 7 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 42% and 50%.
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 47%.
Head to head. These sides have met 4 times in three years, producing over 2.5 goals in 25%. 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 46%.
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 34%, from expected goals of 1.14 for Kocaelispor and 0.92 for Göztepe. Folding in 30% of that view gives 43%.
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 44%.
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.
