I never said it was anything other than highly unlikely, so I agree with you

IIRC, the term I used was "very rare". Hardly alarming. I'm cautious sometimes. If I wasn't, people would find a way to criticise that, too.
But, why would anyone looking for normalised blood sugars deliberately push them up just in case something very rarely seen happened?
@Kamili - My levels have settled where they are aver a period of time, notching themselves downwards as my diet, exercise, BP and my health in general improved. They didn't plummet like a stone.
Your scores look like great progress to me, so I would urge you not to take steps to inhibit your body from finding its natural place, based on a great diet and as much moving around as you can do, or are willing to do. I didn't set out to drive my body to these lows, but once I realised which foods etc., were causing me issues, I just got there over months, not days or weeks.
It is my strongly held belief that many non-diabetics run at the levels I do, but they simply have no idea, because they don't test. Why would they? I would love my OH to were my Libre sensor for one two-week cycle, so observe his curves and numbers. he is a slim fit 68 year old, with recently recorded healthy HbA1c and fasting blood levels, from his regular health check.
Unfortunately, there is little research available out there to read, looking into normo-glycaemia, as I guess that's not exciting or ground-breaking research, and the published data would have a limited audience, I'm guessing.
My personal stance, when something odd crops up is to look for a reason it occurred, rather than immediately associate it. I'm undoubtedly very fortunate to be extremely well and fit both before and since diagnosis, so I tend to naturally reject the association of "everything".
The learning curve we go through in the period after diagnosis is undoubtedly a challenge, but many of us feel we end up healthier in the aftermath than beforehand. My OH, who also adopted the same way of eating (mainly!) has also stated, unprompted, that he feels extremely well on it, and lost around 3-4kg from an already trim frame, but he likes to be lean, so he is happy.
Good luck with what you're doing. It seems you're making great progress, but don't be too hasty to tag every odd or unexpected feeling to your diabetes. There's no doubt diabetes is now part of your overall health picture, but it isn't the only component in it.
