Champions League · Wednesday, 14 October 2026 · 20:00. Final score 3–2 (half-time 0–0). Before kick-off we rated it 54% over 2.5 goals — the match finished with 5, so that call landed. That rating was frozen into a version-controlled ledger before the game and has not been touched since.

The result model puts Real Betis at 29%, the draw at 30% and FC Porto at 42%, from expected goals of 1.01 and 1.61.
The league sets the starting point. Champions League has produced over 2.5 goals in 57% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Real Betis have 3 in 8 this season (1 of 4 at home), FC Porto 5 in 8 (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 52% and 59%.
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 54% and 57%.
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 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 49%, from expected goals of 1.01 for Real Betis and 1.61 for FC Porto. Folding in 30% of that view gives 54%.
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.
