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

| Over 3.5 goals | 39% | 61% | no pick |
| Both teams to score | 48% | 52% | No |
The result model puts Casa Pia at 4%, the draw at 10% and Sporting CP at 86%, from expected goals of 0.64 and 3.22.
The league sets the starting point. Primeira Liga has produced over 2.5 goals in 54% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Casa Pia have 3 in 8 this season (2 of 4 at home), Sporting CP 6 in 8 (3 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 50% and 59%.
Last season still counts, briefly. With 8 and 8 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 48% and 62%.
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%.
Head to head. These sides have met 5 times in three years, producing over 2.5 goals in 60%. 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 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 74%, from expected goals of 0.64 for Casa Pia and 3.22 for Sporting CP. 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 |

| Sporting CP | 8 | 75% | 75% | 75% |
Our numbers give this match a 69% chance of at least one goal before half-time and 37% of two or more. The Primeira Liga rates are 69% and 36%. After the break: 80% for a goal and 44% for two or more (league 79% and 43%). Casa Pia's last 50 games had a first-half goal 66% of the time and a second-half goal 76%; Sporting CP's last 50, 70% and 90%. 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.
