| Market | Yes | No | Our call |
|---|---|---|---|
| Over 2.5 goals | 54% | 46% | Over |
| Over 3.5 goals | 33% | 67% | no pick |
| Both teams to score | 56% | 44% | Yes |
The result model puts Guingamp at 27%, the draw at 25% and Saint Etienne at 48%, from expected goals of 1.21 and 1.69.
The league sets the starting point. Ligue 2 has produced over 2.5 goals in 47% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Guingamp have 6 in 9 this season (4 of 5 at home), Saint Etienne 7 in 9 (4 of 5 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 53% and 56%.
Last season still counts, briefly. With 9 and 9 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 52% and 53%.
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 51%.
Head to head. These sides have met 4 times in three years, producing over 2.5 goals in 100%. 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 54%.
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 55%, from expected goals of 1.21 for Guingamp and 1.69 for Saint Etienne. 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.
| Team | Games | O2.5 | O3.5 | BTTS |
|---|---|---|---|---|
| Guingamp | 9 | 67% | 33% | 67% |
| Saint Etienne | 9 | 78% | 56% | 56% |
Our numbers give this match a 68% chance of at least one goal before half-time and 36% of two or more. The Ligue 2 rates, last season and this season combined, are 66% and 33% (this season so far: 62% with a first-half goal, from 81 games). After the break: 77% for a goal and 42% for two or more (league 74% and 39%). Guingamp's last 50 games had a first-half goal 70% of the time and a second-half goal 80%; Saint Etienne's last 50, 72% and 82%. A goal in both halves: 56% (league 51%). Highest-scoring half: second 45%, first 30%, level 25% — 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.
