Hi Radgirl,
What do you mean with we? Are you talking about pilots, doctors? Critically ill?
The system looks a lot like the Canadian system. They have been doing it for 10 years now. It is still early days so of course they need as much data as possible. The testing regime is designed to minimize hypo's. On non operational days I only measure 2 or 3 times a day.
For flying Continious glucose monitoring is a possibility but not as a primary source. Even with CGM you need do the conventional finger prick testing according to the schedule. It is still early days and I think that the protocol will become less strict (i.e. CGM, testing regime etc)
If you refuse to stick to the protocol the CAA will revoke the medical (understandably) I am more than willing to cooperate in order to make it easier for colleagues in the future!
