Challenge League · Friday, 30 October 2026 · 18:30. Our rating makes this 61% to go over 2.5 goals, so our lean is over. The Challenge League average is 61%.
| Market | Yes | No | Our call |
|---|---|---|---|
| Over 2.5 goals | 61% | 39% | Over |
| Over 3.5 goals | 35% | 65% | no pick |
| Both teams to score | 56% | 44% | Yes |
The result model puts Stade Lausanne-Ouchy at 45%, the draw at 25% and Yverdon Sport at 30%, from expected goals of 1.66 and 1.31.
The league sets the starting point. Challenge League has produced over 2.5 goals in 61% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Stade Lausanne-Ouchy have 4 in 10 this season (2 of 4 at home), Yverdon Sport 4 in 10 (2 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 55% and 55%.
Last season still counts, briefly. With 10 and 10 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 61% and 65%.
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 63%.
Head to head. These sides have met 8 times in three years, producing over 2.5 goals in 75%. 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 63%.
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 57%, from expected goals of 1.66 for Stade Lausanne-Ouchy and 1.31 for Yverdon Sport. Folding in 30% of that view gives 61%.
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 |
|---|---|---|---|---|
| Stade Lausanne-Ouchy | 10 | 40% | 10% | 30% |
| Yverdon Sport | 10 | 40% | 20% | 60% |
Our numbers give this match a 73% chance of at least one goal before half-time and 45% of two or more. The Challenge League rates are 72% and 46%. After the break: 81% for a goal and 52% for two or more (league 81% and 48%). Stade Lausanne-Ouchy's last 50 games had a first-half goal 72% of the time and a second-half goal 80%; Yverdon Sport's last 50, 74% and 84%. 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 · tomorrow.
