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: Strasbourg 6.25, draw 5.50, Paris Saint Germain 1.40.
The league sets the starting point. Ligue 1 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. Strasbourg have 5 in 6 this season (1 of 2 at home), Paris Saint Germain 5 in 6 (3 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 60% and 60%.
Last season still counts, briefly. With 6 and 6 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 60% 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 6 times in three years, producing over 2.5 goals in 100%. 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 54%, from expected goals of 1.26 for Strasbourg and 1.58 for Paris Saint Germain. 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.
