The result model puts Chelsea at 48%, the draw at 25% and Brighton at 28%, from expected goals of 1.59 and 1.15.
The league sets the starting point. Premier League has produced over 2.5 goals in 55% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Chelsea have 0 in 0 this season, Brighton 0 in 0. 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 55% and 55%.
Last season still counts, briefly. With 0 and 0 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 66% and 50%.
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 6 times in three years, producing over 2.5 goals in 100%. 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 62%.
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 52%, from expected goals of 1.59 for Chelsea and 1.15 for Brighton. Folding in 30% of that view gives 59%.
Season opener. One of these sides has not played a league game yet. Openers run about 2.5 points under their league's norm, measured across 2,727 of them, so the rating is docked to 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.
