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: Rayo Vallecano 2.20, draw 3.40, Racing Santander 3.20.

How we got this number

The league sets the starting point. La Liga has produced over 2.5 goals in 50% of its matches, and that is where a team with no record of its own would sit.

Each side's own record. Rayo Vallecano have 2 in 3 this season (0 of 1 at home), Racing Santander 2 in 3 (0 of 1 away). 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 50% and 50%.

Last season still counts, briefly. With 3 and 3 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 40% and 67%.

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 53%.

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 37%, from expected goals of 1.43 for Rayo Vallecano and 0.73 for Racing Santander. Folding in 30% of that view gives 48%.

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.
