Blyth can to an extent get away with it because with it being the terminus of practically all of it's routes, a new bus and driver can be deployed to time correct another service. GNE used to do the same with the TEN at Hexham by having 3941 or 42 ready to go if a late runner came in. The B9 taken off would do the same next or wait another 3 hours to be reallocated if not needed.
Only issue with this is when it happens to the hybrids which in theory shouldn't happen but it does.
