Every remaining fixture is simulated with a Poisson model: each club gets an attack rating and a defence rating from the goals it has scored and conceded this season, and the expected goals of a match come from combining one side's attack with the other's defence, plus a moderate home advantage.

Before a ball is kicked the model does not start from zero: each club begins with a prior strength built from last season's finish and the market value of its squad, with the tails capped so no extreme is absurd. That starting point hands over weight to real results as they arrive, and by around matchday ten only the actual goals are talking.

The remaining season is played 10,000 times in a separate browser process, so the page never freezes. The title, top-four, top-six and relegation percentages are simply how often each outcome happened across those 10,000 seasons, and each club's points range covers the central 90% of its simulated finishes.

What the model does not know: injuries, transfers, sanctions, European fixtures or motivation. It uses goals and only goals — which is why it is in beta.
