I agree that the system with SRG and NATS isn't what it could be, however "The NATS/SRG relationship seems to be one where NATS says it is OK and SRG has to prove otherwise!" Uuumm, how can it be otherwise? I may be misinterpreting what you've said but surely you say to someone ' Here's what I've built and its great, works perfectly!' and its then up to them to say 'Well lets see how the brakes work, prove that they do!' I don't see how you prove something when no-one challenges you as to what works and how.
I know that the ATSSD took a keen interest in everything that was going on in the run up to 'O' date and subsequently. Many letters of challenge were sent to the NERC management team and they had to prove that what they were challenged on was correct or provide mitigation.
10% light on ATCO's accords with what I've heard for most watches. When you figure in another 10% sickness (including the long term) on a couple of watches that equals, uumm, well a LOT more than 12 short!
