In all honesty, it is more cost-effective for the operator that way, but a more frequent service with single deckers is probably more convenient for passengers.
The overall PVR hasn't changed drastically, so I think it's mainly been about shuffling the pack to utilise frequency and capacity more effectively. Whilst some have seen their frequency reduce, others have seen theirs increase.
