Gameweek 3

In GW3 the model missed by 2.30 points a player across the 199 likely starters it scored, and the real team scored 56.

There’s one of these for every settled GW, good or bad, and I don’t touch them once they’re up. The misses are at the top, and everything they’re worked out from is further down.

Where Gameweek 3 went wrong

  • Its ordering of the players barely matched the week's: rank correlation 0.16, where 1.00 would be a perfect order and 0 no relationship at all.
  • Spotting 10+ hauls was no better than a coin toss this week. It came out at 64% and the interval runs from 46% to 80%, and takes in 50%.
  • The team finished 1.3 behind a sample of top-10k managers (average 57.3, 170 sampled). This early, the sample is chosen on the very weeks it is scored on, so the gap is overstated.
  • The best team the model could legally have bought scored 51, 40% of the 127 a perfect-hindsight XI would have made.

What went right

  • Better than usual this week - the model was out by 2.30 points a player, against 2.44 across the season so far.
  • The model was closer than last season's points per game on points per player: 2.40 to 2.48 on the 156 players both scored.
  • The model was closer than last season's points per game on the big misses: 3.08 to 3.25 on the 156 players both scored.
  • The model ordered the players better than last season's points per game: 0.20 to 0.07 on the 156 players both scored.
  • The model was better than last season's points per game at spotting 6+ hauls: 68% to 56% on the 156 players both scored.
  • The model was better than last season's points per game at spotting 10+ hauls: 64% to 43% on the 156 players both scored.
  • The model ordered the players better than top-10k effective ownership: 0.16 to 0.09 on the 199 players both scored.
  • The model was better than top-10k effective ownership at spotting 6+ hauls: 69% to 55% on the 199 players both scored.
  • The model was better than top-10k effective ownership at spotting 10+ hauls: 64% to 49% on the 199 players both scored.
  • The team scored 56, 5 above the average manager's 51.

Not available this week

  • Only 42 players scored 6+ this week, too few to claim a result on the 6+ figure.
  • Only 12 players scored 10+ this week, too few to claim a result on the 10+ figure.

Prediction vintage: 4 Sept, 16:27 UTC run · Predictions are from the last model run before each gameweek's deadline (90 minutes before the first kickoff). A gameweek marked 'seed' is from before I kept the runs, so it's scored against the pre-season predictions I committed.

95% percentile intervals from a row-level bootstrap (1000 resamples, seeded). Player-fixtures in the same GW share fixtures and clean sheets, which makes these intervals understate the true width - read them as a floor on the uncertainty. Fewer than 50 hauls is too few to claim a result from a haul AUC.

The same error on every group of players

I never show the every-player figure on its own (SPEC §1.6), so all four are here. Whichever group you think is the right one, my number for it is on the page - just compare it with other people's on the same rows.

Against the comparators

The model's error next to a comparator's, on the same rows. If a comparator can't cover every row the model scored, I drop the rows it's missing and re-score the model on what's left. The model's headline number for the week isn't part of the comparison.

Comparator
Last season's points per game

Each player's total FPL points last season divided by his appearances, which is the number most of us reach for before a ball is kicked.

Different rows. This comparator scored 156 of the model's 199 rows for this GW; 43 of the model’s rows are left out because it has nothing to say about them. Every “model” number in this table is the model re-scored on exactly the 156 rows it covers. Its headline error for the GW (2.30, over 199 rows) is not the one to read against this comparator.

Population: reference arm's predicted E[minutes] > 60, imposed on every arm (n=156 of 401 player-fixtures); players with a prior-season appearance only

A dash means there’s no figure for that metric from this comparator, which isn’t the same as a zero. “No direction stated” means the data doesn’t say which way is better for that metric, and without that I don’t call a winner.

Comparator
Top-10k effective ownership

How much the top-10k sample owned each player at the last capture before the deadline, including captaincy. It doesn't come with a points prediction so I only score it as a rank.

Rows covered. This comparator scored 199 of the model's 199 rows for this GW, with none of the model’s rows excluded. Every “model” number in this table is the model re-scored on exactly the 199 rows it covers, which is the only like-for-like comparison.

Comparator
FPL's own projection (ep_next)

The expected-points figure FPL publishes for each player before the GW, captured between the previous deadline and this one. It's a per-GW number and can't tell you anything about the second game in a DGW, so like the ownership figure I only score it as a rank.

Different rows. This comparator scored 0 of the model's 199 rows for this GW; 199 of the model’s rows are left out because it has nothing to say about them.

How the comparators are scored Lower is better for MAE and RMSE, and higher is better for Spearman and haul AUC. Which way is better is stored with each metric and the verdicts just follow that. Each baseline is scored on the model's own likely starters (expected minutes over 60) and reports the model's score over those same rows, which keeps the two numbers like for like even when the baseline can't cover every row. Overall Spearman and AUC are averages over the GWs where both sides have a value. I don't pool them across gameweeks, because that would rank a GW1 blank against a GW7 haul.

Legal-squad Team of the Week

Picked from the last model run before the deadline, at the prices captured before it, then scored on what actually happened.

Not comparable with the real entry. A fresh £100.0m squad bought from scratch every gameweek - it never pays a transfer hit or banks a price rise and nothing carries over from the week before. Think of it as a weekly check on the model's picks within the real squad rules. Nobody could run a team this way in practice, so it's not comparable with a managed entry.

Where these numbers come from

Predictions are from the last model run before each gameweek's deadline (90 minutes before the first kickoff). A gameweek marked 'seed' is from before I kept the runs, so it's scored against the pre-season predictions I committed.

Population scored: predicted E[minutes] > 60 (n=199 of 618 player-fixtures).

This page is a slice of the same /performance/live payload that drives the full record, which means a GW page and the season page can’t disagree. The projections themselves are published in full at /data/gw/3.

The exact rows this GW was scored on (the last run before the deadline, as it was served) are at fpl-quant-api.fly.dev/performance/live/gw/3/predictions with sha256 6f8b387e…5a77. The digest is of the rows array alone as compact JSON (no whitespace), rows sorted by player then fixture, and the response says so beside it. You can recompute any number on this page from them.

What this record measures, on which rows, against which comparators and at which checkpoints was fixed in advance: the pre-registration (sha256 27307797…ba4f, checkpoints GW10, GW19, GW38).

Every settled gameweek has a page: GW1, GW2, GW3, GW4, GW5, GW6, GW7, GW8.
