The result model puts Benfica B at 46%, the draw at 27% and Chaves at 27%, from expected goals of 1.48 and 1.08.
The league sets the starting point. Liga 2 has produced over 2.5 goals in 45% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Benfica B have 2 in 7 this season (0 of 4 at home), Chaves 4 in 7 (2 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 41% and 48%.
Last season still counts, briefly. With 7 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 44% and 41%.
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 43%.
Head to head. These sides have met 4 times in three years, producing over 2.5 goals in 25%. That nudges the number 5% of the way toward the head-to-head pattern — deliberately small, because fixtures change more than reputations do — landing on 42%.
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 47%, from expected goals of 1.48 for Benfica B and 1.08 for Chaves. Folding in 30% of that view gives 44%.
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 45%.
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.
Our numbers give this match a 66% chance of at least one goal before half-time and 28% of two or more. The Liga 2 rates, last season and this season combined, are 66% and 27% (this season so far: 75% with a first-half goal, from 63 games). After the break: 78% for a goal and 42% for two or more (league 75% and 41%). Benfica B's last 50 games had a first-half goal 70% of the time and a second-half goal 78%; Chaves's last 50, 64% and 88%. A goal in both halves: 53% (league 51%). Highest-scoring half: second 45%, first 28%, level 27% — close to the league's usual split, because team form says little about which half is busier. Team form says less about a single half than about a full match, so these numbers stay close to the league's.
Every match ranked the same way: first half goals today · second half goals today · goal in both halves today · tomorrow.
