The result model puts Slavia Praha at 41%, the draw at 31% and Arsenal at 28%, from expected goals of 1.46 and 0.9.
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. Slavia Praha have 7 in 11 this season (5 of 6 at home), Arsenal 4 in 7 (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 59% and 57%.
Last season still counts, briefly. With 11 and 7 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 58% 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 57%.
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 42%, from expected goals of 1.46 for Slavia Praha and 0.9 for Arsenal. Folding in 30% of that view gives 52%.
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 53%.
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.
