| Market | Yes | No | Our call |
|---|---|---|---|

| Both teams to score | 54% | 46% | Yes |
The result model puts Barry Town at 65%, the draw at 20% and Trefelin at 15%, from expected goals of 2.2 and 0.96.
The league sets the starting point. Cymru Premier 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. Barry Town have 10 in 13 this season (5 of 6 at home), Trefelin 7 in 13 (4 of 7 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 63% and 54%.
Last season still counts, briefly. With 13 and 13 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 58%.
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 55%.
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 61%, from expected goals of 2.2 for Barry Town and 0.96 for Trefelin. Folding in 30% of that view gives 57%.
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 |
|---|---|---|---|---|
| Barry Town | 13 | 77% | 69% | 77% |
| Trefelin | 13 | 54% | 38% | 46% |
Our numbers give this match a 74% chance of at least one goal before half-time and 41% of two or more. The Cymru Premier rates are 74% and 38%. After the break: 78% for a goal and 52% for two or more (league 77% and 50%). Barry Town's last 50 games had a first-half goal 70% of the time and a second-half goal 74%; Trefelin's last 44, 77% and 89%. 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.
