9 matches is a small sample — these averages are noisy and should not be read as a tendency.
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.
When the model has said 45–50% in the past, 1,541 of 3,251 predictions were correct (47.4%). Accuracy record →

The measurements our data provider sent for this match. A row that was not measured shows “—”; writing 0 into an empty field would claim we measured it and found none.
When the model has said 40–45% in the past, 469 of 1,102 predictions were correct (42.6%). Accuracy record →
These three values add up to 200%, not 100% — and that is not a mistake. The options are not mutually exclusive; every outcome is counted in two of them. For the same reason 1X plus X2 exceeds 100% by exactly the probability of a draw (27.5%).
The 3+ goals prediction is not published for this match.
The model gives a probability below the baseline (54.1%). In backtesting the model's edge in the "fewer goals" direction could not be confirmed; we don't publish an unconfirmed prediction.
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.
Attack: Nottingham Forest score below the league average (15% fewer).
Opponent's defence: FC Porto concede 44% below the league average — a defence that seriously brakes even a strong attack.
Result: These two effects give an expectation of 0.91 goals (including home advantage).
Attack: FC Porto score above the league average (38% more).
Opponent's defence: Nottingham Forest'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 1.31 goals (including the away penalty).
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.
Ratings were computed from 2636 matches played in this league before kick-off; the team with fewer has 131 matches. No data from after the match was used. The model's track record is published unfiltered.
