It is, but I'd suggest its better to have a reliable service across a 15 minute frequency than to have an unreliable service at a 10 minute frequency.

Also as each bus is busier journeys need more running and layover time (to cope with the extra time it takes to load and unload a busier bus) but GNE rarely increase these.

Yes, and on something like the 20, on an already reduced frequency, there's now the removal of two buses per hour (X20) with no additional running time to compensate for that. The 20 is already problematic for time-keeping, especially in and out of Durham, without this extra curveball being thrown.

I'm also not convinced switching back to 20/20A is a wise move. I recall this caused problems last time round, as those for Fencehouses, Rainton Bridge or Hall Lane Estate kept ending up on the wrong bus. A problem that is now going to be introduced into Durham, with some buses heading up to the Arnison Centre and Langley Park. 

Perhaps a better solution would have been reducing the 20 frequency and keeping the established X20 in place, along with the separate branding and service number.
