With a bigger frequency comes more costs (insurance, various equipment a company uses to track vehicles etc, destination display equipment, drivers' wages etc).
The 10 is probably a good example of that (cant think of ANE examples off the top of my head).
If you think about when it was all single deck operation and ran on the greater frequency between Hexham and Newcastle - compared to the current frequency on the deckers, with a smaller PVR, but similar seats per hour on the route.
I imagine costs equated to wages etc are better currently, but that could be reduced slightly, with it costing more per hour to run a bigger vehicle as well as the greater purchase price.
