How it works

What we do, what the numbers mean and how good they really are. The short version comes first; the full detail is further down for anyone who wants it.

The idea in one minute

We forecast every match

A statistical model estimates the chance of each result, of more than 2.5 goals and of both teams scoring, using only what was known 24 h before kick-off.

We lock it before the match

Each forecast goes into a record that can only grow: it is never edited, and a correction is a new line. We publish a fingerprint of each line, so nobody can rewrite the past, including us.

We play out the season

The matches left are simulated thousands of times. That gives each club its chance of the title, Europe or relegation, and it is what the simulator uses when you pick results.

We check ourselves against the market

The closing odds of the bookmakers are the hardest yardstick there is, so that is what we measure against, and we show the result whatever it says. This is a personal project, and nothing here is betting advice.

What the numbers mean

41 in 100
If this match could be played 100 times, that is how many times it would end this way. It is a chance, not a promise.
Favourite
The result we think most likely, even at 40 in 100. Being the favourite does not mean being more likely than not.
Right and Wrong
Whether our favourite result happened. It is a simple reading: a favourite at 40 in 100 that loses is not necessarily a bad forecast.
Test forecast
Made after the match was played, to test the model. It proves nothing and does not count towards our record.
Simulated seasons
The rest of the season played out by computer, result by result. The simulator keeps only the simulations with the results you pick, so with many picks few are left and the numbers get rough; it tells you when that happens.
Closing odds
The last prices of the bookmakers before kick-off, with their margin removed. We use them to measure ourselves, not as a tip.
RPS
A score for a home, draw or away forecast: the closer to what happened, the lower. A small difference in RPS can be a big difference in quality.
Calibration
Whether the numbers mean what they say: of all the times we say 70 in 100, about 7 in 10 should happen.
Holdout
Seasons kept aside and tested only once, at the end, with the model already fixed, so the test cannot be tuned to look good.
Ledger
The record of forecasts. Lines are only ever added, and only those written before their match count.

So how good is it?

The test that counts: two whole seasons kept aside and opened only once, with the model already fixed. Beating the closing odds is very hard, and a model built on public data is not expected to. Here is what came out.

Calibrated probabilities for every match (1X2, over/under 2.5 goals and both teams to score), frozen 24 h before kick-off in an append-only ledger and scored against the no-vig closing market.

Both teams to score is shown for completeness: it has not beaten the base rates, neither in development nor on the holdout.

Status as of 2026-11-11 (UTC).

The model is not distinguishable from the closing market.

Over 612 matches of 2024/25 and 2025/26, opened once with the model fixed in a commit, the RPS of phase4-v1 minus the market's is +0.0041 [-0.0002; +0.0089] (95% interval). Below zero would mean beating the market.

What we said and what happened

What we said and what happened

If the probabilities on this page are right, adding them up says how often each thing should happen, and chance alone still moves the real count around that number. The shaded band is where the count lands 9 times out of 10 when the probabilities are right: a result outside it is a warning sign, one inside it is not proof. These are the phase4-v2 forecasts shown above, one per match; the comparison with every model and the baselines is in the live record.

Reliability diagrams

Forecasts grouped in five bins of 20 points. A point on the dashed diagonal means things with that probability happened exactly that often; the shaded bar is the 90% band chance allows in that bin, so a point outside its bar is the warning sign. The three 1X2 outcomes of a match are pooled, which makes the band a little too narrow.

Mean RPS of phase4-v2 minus that of the no-vig closing market in each round (a Tuesday-to-Monday week). Below zero the model was closer to what happened. The model was better in 0 of 3 rounds; one round is a handful of matches, so the overall verdict is the live record's, not this count.

The two most recent seasons were kept closed while every model choice was made, then opened once with the model fixed in a commit. Walk-forward: each forecast uses only data available 24 h before kick-off. 95% intervals from a weekly block bootstrap. Differences are model minus the closing market; negative is better.

Method

Method

Every external datum carries the moment it became available, and a forecast only uses what existed 24 h before kick-off; an automated test fails if a feature breaks this. Models are trained walk-forward on earlier matches only. The ledger is append-only JSONL in git: a correction is a new line, never an edit. The scores above are derived from the ledger, the results and the closing odds; nothing is written back.

RPS (ranked probability score) is the primary 1X2 metric because it respects the order home, draw, away; log loss and Brier are secondary. The closing market has its margin removed with the power method for 1X2 and proportionally for over/under.

Open data

The numbers on this page are also published as JSON, free to reuse under CC BY 4.0 with a credit to this site: one forecast per match, with results once played, and the season table with every final position and the head to head. index.json describes the files. Bookmaker odds are not included: their sources do not allow redistribution.

Every ledger line also has its SHA-256 in ledger-hashes.json. The ledger stays private because it holds odds, but this site's public git history dates each hash: anyone later shown a line can hash it and check that it was published, unchanged, before the match.

Every match, in detail

Open forecasts

Frozen before kick-off and not played yet, soonest first. Fair odds are 1/p, with no bookmaker margin. Exact scores come from the Dixon-Coles score grid, adjusted so its 1X2, over 2.5 and both-score totals equal the numbers on the card. Kick-off in Lisbon time. One forecast per match, from phase4-v2, the current model; the other versions in the ledger are compared in the live record.

No frozen forecast is waiting for kick-off. The scheduled job freezes each match 20 to 24 h before it starts.

Waiting for the result

These matches have started or finished, but their result is not in the data yet: results come from football-data.co.uk, which updates its file a few times a week. They are scored as soon as it arrives.

The season, in detail

Season 2026/27: how the table may finish

The table after 98 results, with the 208 matches left simulated 50,000 times (data to 2026-11-09, UTC). Each club's strength comes from the market's odds on its recent matches and may drift until May; scores follow the Dixon-Coles grid, and ties the league's rules. Frozen in the season ledger as season-s2-v1 after every new result.

Ordered by expected final points. Each place once, as the league allocates it, without the cup: the champion and 2nd go to the Champions, 3rd to its qualifying rounds, 4th to the Europa League and 5th to the Conference League; 16th plays the relegation play-off and 17th and 18th go down. Each row adds up to 100, and an empty cell means less than 1 in 100. The bar is the central 80% interval of the final points and the mark its mean. Each club's name opens its page, with every final position and the head to head with each rival.

What the next matches put at stake

For each match of the next week, the season chances that move most with its result. They are counted again in the simulations that drew each result, so several matches stay consistent with each other; the percentages under the teams are how often the simulations drew each result.

Can these numbers be trusted?

Before anything was published, the same simulator was tested on 2017/18 to 2023/24 at six moments of each season, with the holdout untouched. The final points fell inside the 80% interval 84% of the time and inside the 90% one 91%.

Clubs leading by 3 points or more were given 85% on average to win the league; 88% of them did (16 cases).

Final-position RPS 0.0712, against 0.0736 for the same simulation driven by Elo (lower is better; the difference is within the noise of seven seasons). A chance is not a promise: a club at 50% misses half the time.
