So for something like the 335/351/359 it's as simple as adding all 3 routes up then doubling it to reflect both directions as they work in a line. Then dividing it by 60 as it's only 1 BPH. If it's more frequent then you'd times it by the number of buses an hour before dividing it.

For interworking services, you'd generally just add everything together so for the X7/X8/X9 at Blyth you'd just work out the time to do an X7, an X8 and an X9 and doubling that instead.
