How the numbers for Bristol Rovers v Chesterfield are calculated
Every figure on this page comes from the steps below – nothing is adjusted by hand.
Expected goals (λ)
Not enough history for team ratings – the goal estimate uses the statistical feed and the market line only.
| Total-goals source | Estimate | Weight |
|---|---|---|
| Statistical xG feed | 3.04 | 45% |
| Over/under 2.5 price | 2.89 | 55% |
| Blended total λ | 2.96 | 100% |
Split by team strength and the 1X2 balance → λhome = 1.34, λaway = 1.62
Poisson goal distributions
P(k goals) = e−λ · λk ÷ k!
Score grid
Each cell = P(home goals) × P(away goals). Below the diagonal is a home win, the diagonal a draw, above it an away win.
