Premiership · Saturday, 17 October 2026 · 20:00. Final score 2–2 (half-time 1–1). Before kick-off we rated it 54% over 2.5 goals — the match finished with 4, so that call landed. That rating was frozen into a version-controlled ledger before the game and has not been touched since.

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: Dundee 6.50, draw 4.75, Rangers 1.44.
The league sets the starting point. Premiership has produced over 2.5 goals in 53% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Dundee have 4 in 8 this season (2 of 4 at home), Rangers 3 in 8 (1 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 52% and 49%.
Last season still counts, briefly. With 8 and 8 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 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 54%.
Head to head. These sides have met 10 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 55%.
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 54%, from expected goals of 1.07 for Dundee and 1.77 for Rangers. Folding in 30% of that view gives 54%.
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 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.
