Have you ever used the service, or just photographed it by the side of the road? Due to the nature of the service, the bus can often be stood stationary for 5 minutes while the driver assists tourists/walkers. There's enough slack in the timetable to allow drivers to do that!
Have to agree here about the AD122 timetable being slack, when I rode the full route on Easter Saturday it was a steady ride with a fair amount of waiting time taking place at various points in the route and the driver even advising a passenger advising a passenger what time the buses headed back to Hexham, it still arrived at Haltwhistle Rail Station on-time. Admittedly the bus was lightly loaded with no other passengers boarding the route during my journey.
As for the roadworks in Durham at the moment, it's difficult to compare the timekeeping between services where apart from the area where the roadworks are, the routes are a completely different kettle of fish and there could be other factors which is causing delays to the service, for example the Sapphire 22 is still having to take a small diversion around by Dalton Park and the X12 has also had to contend with works in Low Fell and Gateshead whereas other than Durham I don't think there is really anything else out of the norm that could currently impact the timekeeping on the 20/20A/X20.
