Port Vale vs Chesterfield
Our model puts a Port Vale win at 39.7% in this League Two fixture — close to a three-way split. Expected goals run 1.36 to 1.23.
What this probability has been worth
A number is worth what it has been worth. Across 1,941 predictions published before kick-off and scored against the result afterwards, the calls we priced between 35% and 45% came in 38.8% of the time — 717 fixtures in that band. The model claimed 40.6%, so the two are within 1.8 points of each other. In this range the stated probability has meant roughly what it says.
Where we disagree with the market
Bookmakers price Chesterfield at 2.4, which implies about 41.7%. Our model has it at 33.8% — 7.9 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.
Port Vale are off their season peak
Port Vale peaked at 1500 this season and sit at 1444 today, 56 points below their own best. Measuring a side against itself rather than against the table is often the earlier signal, and it is not visible in a league position.
How often they shoot
Chesterfield take 15.7 shots a match against an average of 11.9. Volume like that usually means territory rather than precision, and it is why a side can dominate a match and still not win it.
Early or late
76.9% of Port Vale's goals have come after the break, against 56.2% for the sides we measure, over 13 goals. A side that scores this late is usually one that grows into matches or finishes them stronger than it starts — and one whose half-time score says less than usual about the result.
