Decision weights

Missing resort data remain eligible: unavailable evidence is omitted and confidence falls instead of the resort receiving a zero.

How Benchmark works

Priorities determine the structural ranking; optional trip context refines those priorities without excluding a resort. Evidence describes data support, Stability tests nearby priority changes, and Frontier marks a non-dominated option on comparable evidence.

Trip contextOptional

Use these only when they matter for this trip. They adjust ranking and interpretation; they are not hidden filters.

Travel origin is preserved with the decision state; access scoring uses the selected arrival hub when one is chosen.

Side-by-side evidence

Detailed comparison

Structural snow resilience uses the multi-winter early/core/late archive after daily de-duplication. Calendar-date rows separately compare current observations with the previous five years. Missing archive evidence remains unknown.
