Today I seen two 56 going towards Gateshead Interchange from Sunderland within 5 mins of each other, at around 17.00. Both NIS.

All four buses looked like they had a handful of passengers on, so I can only assume they were being "regulated".

Does all use of 'Not in Service' get reported on?

I'm on my phone, so it is a faff downloading documents from the internet, to then upload back on here.
Just googled 'vosa procedures for reporting pcv punctuality' and there are some interesting documents available to view.
