(*) After the degradation even CRM is "inside the loop". A highly unpredictable "System (a/c) performance"
If I understand this statement as meaning that human in the loop leads to unpredictability, I agree with you. However, unpredictability doesn't always imply unreliability. It may be possible to design more reliable systems by having humans in the loop well before degradation or even continually. The challenge will be to come up with an interface.
