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: Hamburger SV 2.50, draw 3.50, FSV Mainz 05 2.55.

How we got this number

The league sets the starting point. Bundesliga has produced over 2.5 goals in 64% of its matches, and that is where a team with no record of its own would sit.

Each side's own record. Hamburger SV have 0 in 1 this season, FSV Mainz 05 0 in 1. Those records are pulled toward the league rate with the weight of about 32 matches — enough that two or three unusual games cannot swing a rating — giving 62% and 62%.

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 14 — the point at which our testing showed they stop adding accuracy. That moves the two figures to 56% and 54%.

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 57%.

Head to head. These sides have met 2 times in three years, producing over 2.5 goals in 50%. That nudges the number 10% 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 55%, from expected goals of 1.71 for Hamburger SV and 1.19 for FSV Mainz 05. Folding in 30% of that view gives 56%.

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.
