Gimnasia (Mendoza) vs Newell's Old Boys
Our model puts a Gimnasia (Mendoza) win at 47.6% in this Liga Profesional Argentina fixture — a moderate lean. Expected goals run 1.6 to 1.15.
What this probability has been worth
A number is worth what it has been worth. Across 1,832 predictions published before kick-off and scored against the result afterwards, the calls we priced between 45% and 55% came in 46.8% of the time — 554 fixtures in that band. The model claimed 49.5%, 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 the draw at 3.05, which implies about 32.8%. Our model has it at 25% — 7.8 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 — 1508 against 1514, 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.
Newell's Old Boys are hard to beat
Newell's Old Boys have gone 7 matches without losing, though without stringing wins together. That pattern tends to push draw probability up more than it pushes a win probability.
