Two sides the ratings cannot separate
Rio Ave carry a model rating of 6.49 against 6.57 for Nacional. The scale is anchored so that an average side in one of Europe's big five leagues sits at 6.85, and it is adjusted for the strength of each team's league, so the two numbers are comparable even across borders.
A gap that small is inside the noise of the rating itself — treat the two as level.
What the model expects
Under the hood the model expects 1.34 goals for Rio Ave and 1.30 for Nacional. Those two numbers, not the scoreline, are what the model actually estimates; everything else is derived from them.
Rio Ave rate 0.68 in attack and 1.40 in defence, where 1 is league average and a lower defensive number is better; Nacional rate 0.74 and 1.30.
Where the model differs from the table
The table and the model disagree here: the standings favour Nacional, while our numbers lean the other way. The model weights recent expected goals rather than results already banked, so it moves before the table does.
How this was produced
Publicly tracked record so far: 1344 correct results out of 2888 settled predictions (47%), with 275 exact scorelines (10%). That log is updated automatically after every match and is never edited.
Full method: how the model works.
From the first whistle this page keeps going: the win probabilities at the top are recalculated as the match plays out, reading the score, the clock and any sendings-off. The same model, asked how many goals are left rather than how many there will be.
