Atlético Nacional vs Atlético Junior
Our model puts an Atlético Junior win at 40.6% in this Colombian Primera A fixture — close to a three-way split. Expected goals run 1.62 to 1.72.
What this probability has been worth
A number is worth what it has been worth. Across 1,536 predictions published before kick-off and scored against the result afterwards, the calls we priced between 35% and 45% came in 37.9% of the time — 589 fixtures in that band. The model claimed 40.6%, so the two are within 2.7 points of each other. In this range the stated probability has meant roughly what it says.
Where we disagree with the market
Bookmakers price Atlético Nacional at 1.48, which implies about 67.6%. Our model has it at 36.2% — 31.4 points lower. That is a wide gap, and it is worth being plain about what it means: it is not a claim that the price is wrong and we are right. It means two methods that usually agree have landed far apart on this one, and only the result will say which of them read it better.
Evenly rated
There is almost nothing between these two on rating — 1495 against 1490, a gap of 5 points. Fixtures this evenly matched are where a model has least to say: the probabilities below are honest, but they are close to a coin weighted only slightly.
