How well did the model do?

48 teams. 16 cities. 104 matches played — and Spain lifted the trophy, the model's most likely champion since before the opening match. Every pre-match prediction is now lined up against every actual result in the calibration report.

Three lenses: travel & jetlag, opponent strength, and advancement odds. Pick the question you care about.

How the difficulty scores work

The Edge Index ranks all 48 teams on travel difficulty using 9 factors: total kilometres flown, time-zone shifts, number of venue changes, altitude swings, expected heat, climate variance, rest days between matches, circadian penalty (kickoff time vs. body clock), and host advantage. Each factor is normalised across the field; higher score = harder schedule (0–100 scale).

Opponent Difficulty is the average Elo rating of each team's three group opponents, also normalised 0–100. The Combined Difficulty averages the two — harsh travel plus tough opponents equals the toughest road.

Advancement probabilities came from a Monte Carlo simulation of 10,000 tournaments: every match sampled from a Poisson goal model (mean driven by Elo difference), with real results replacing simulated ones as the 104 games were played.
