What this probability has been worth
A number is worth what it has been worth. Across 1,564 predictions published before kick-off and scored against the result afterwards, the calls we priced between 45% and 55% came in 45.4% of the time — 476 fixtures in that band. The model claimed 49.6%, so the two are within 4.2 points of each other. In this range the stated probability has meant roughly what it says.
Where we disagree with the market
Bookmakers price Newell's Old Boys at 2.75, which implies about 36.4%. Our model has it at 48.4% — 12 points higher. 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.
