The bar is the model's probability; the caret on the same scale is the market's, with the margin removed. The distance between them is the disagreement.

Model fair prices, computed as 1 / probability from a Dixon-Coles score matrix. No bookmaker margin is included, and no bookmaker is quoting these. A real price will be shorter than every number here.

Thin sample

Coventry City has only 8 completed matches in the training window, so its fitted strength is imprecise. Treat the long prices in this book as arithmetic rather than information: a real bookmaker would quote a much shorter price on the outsider.

What is driving this

computed, not generated

Computed arithmetic, not generated text. Each driver is a stored quantity: the Elo difference replayed from results, points per game over the last five matches, rolling expected goals, and each absent player's share of team expected goals.

Unavailable players3% home against 25% away xG missing
Favours EVE. 0 out and 7 doubtful for EVE, 6 out and 4 doubtful for COV; measured as the share of recent expected goals those players contributed
Underlying expected goals+0.78 net xG per match
Favours EVE. EVE +0.20, COV -0.58 across the form window — results are noisier than the chances behind them
Home advantage+60 Elo equivalent
Favours EVE. the football default is around 100 Elo points, but Premier League home advantage fell during the crowdless 2020/21 season and settled lower afterwards, so the ratings carry a smaller term
Team rating gap+49 Elo
Favours EVE. EVE 1525 against COV 1476, computed from stored results; an Elo-driven model scores RPS around 0.2015 on this league against roughly 0.194 for de-vigged closing odds
Recent form1.00 against 1.20 points per game
Favours COV. last 5 and 5 completed matches: LLDWD against LLWWL

Re-price without a player

Removing a player scales that side's expected goals by their share of recent attacking output, then rebuilds the score matrix. Every market moves together.

Written summary

generated text

Written by gpt-5.6-terra from the numbers above, which it cannot add to or override.

The model gives Everton a 46.0% win probability, with the draw at 32.6% and Coventry City at 21.4%. Expected goals are 1.17 for Everton and 0.71 for Coventry. The 29.2% over-2.5-goals figure and 36.0% both-teams-to-score figure point to a low-scoring model profile. The market is more positive on Everton, pricing their win probability at 55.7%, against the model’s 46.0%. It gives the draw 24.6% and Coventry 19.7%, both below the model’s 32.6% and 21.4%. The scorecard says the model does not beat the closing market, so these figures do not indicate an edge over it. Everton’s last 5 matches brought 1 win, 2 draws and 2 losses, with 3 goals from 8.3 xG. Coventry have 2 wins and 3 losses, scoring 6 from 5.0 xG. There are no named missing players, but 7 Everton and 10 Coventry absentees have no measurable output-share estimate, so their effect is unknown.
