Model prediction

Why this prediction?

The model puts the most likely outcome at 66.5%: “SC Braga to win”. Second comes “a draw” at 20.6%.
Behind that distribution are the expected goals: 2.13 for SC Braga, 0.88 for Estrela.
The highest double chance value is 87.1% (1X — SC Braga win or draw).
These values were computed from 619 past matches.

This is a prediction, not a guarantee; a probability is not a certainty.

These sentences are built by a fixed template; every number in them comes straight from the model's computation, none invented while the text was written.

These values are not a fraction of the full-match prediction; they come from a separate model trained on the first-half scores of 619 matches. Its edge over the base rate is markedly smaller than the full-match model's — the measured figure is on the accuracy record. Read them more cautiously. First-half goal markets are not published because they failed to beat the base rate.

Expected fouls and corners

Fouls

SC Braga: at least 11Actual: 14
Estrela: at least 11Actual: 9

Corners

SC Braga: at least 5Actual: 13
Estrela: at least 3Actual: 4

These figures are set to hold in at least 60% of matches; in the rest the count comes in below them. No upper bound is stated — we make no "at most" claim. Yellow cards were measured and are not published: there our model did not beat the historical average.

What these probabilities rest on

Expected goals comes out of a team's attack weighed against its opponent's defence. A strong attack is damped when it meets a strong defence — which is why comparing the ratings on their own is misleading.

How many goals SC Braga score2.26

Attack: SC Braga score above the league average (41% more).

Opponent's defence: Estrela's defence is close to the league average (1.09×), so it doesn't move the expectation much.

Result: These two effects give an expectation of 2.26 goals (including home advantage).

How many goals Estrela score0.87

Attack: Estrela score below the league average (16% fewer).

Opponent's defence: SC Braga's defence is close to the league average (0.97×), so it doesn't move the expectation much.

Result: These two effects give an expectation of 0.87 goals (including the away penalty).

Most likely scorelines

2–011.5%2–110.9%1–110.3%

A single scoreline is always less likely than an outcome: “home win” is the sum of 1-0, 2-0, 2-1 and dozens more. So the most likely single score can be a draw while the most likely outcome is a home win; the two do not contradict each other.

Week 1 of the season. This prediction was computed from previous seasons. Summer transfers, budget changes and squad rebuilds aren't in the ratings yet — the model can only see that a team has been rebuilt once new results come in.

We measured this and we're not hiding it: in the opening week of past seasons the model came in 3.3 points below the accuracy it claimed (n=220) — for the rest of the season it beats its own claim. The tendency points this way, though it is not proof on its own: in the opening week it slightly over-calls home wins (said 42.7%, got 39.5%) and slightly under-calls draws (said 26.1%, got 28.2%).

This sample is small and not statistically established, which is why we do not correct the model for it. The correction we tried (pulling probabilities toward the league average) didn't win on holdout, so it wasn't added. Read opening-week predictions with a little more caution.
