Why

Andorra narrowly leads because of good terrain match · 74/100 — led by strong terrain profile and substantial ski-area scale; partial evidence, good reliability match · 76/100 — led by strong snow resilience; partial evidence. Chamonix is the strongest alternative. 3 options remain on the Pareto frontier. 1 option have limited evidence coverage.

Limited evidenceUpdate time unknown

Structural fit score: 75/100.

Evidence coverage is limited; the ranking may move with new observations.

AlternativeChamonix

Main uncertaintyThe lead over Chamonix is small. Some requested evidence is unavailable; the score is rescaled over the evidence that exists.
