Would that not normally be enough to justify? I can think of a good handful of routes that have deckers, yet can't really justify them for half the route. ANE X1/X2 being a good example, and GNE's X1 being another. To me, if you've got mass standees for a 10 mile stretch, then it's a problem that needs resolving.
