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.
