Absolutely agree.
I had a sub 40mmol/mol HbA1c once, but it almost killed me to get there. I was absolutely obsessed with testing and could not stop thinking about "what my BG might be". There was little quality of life, although at the time it felt sound - it really wasn't.
I had an interesting discussion with my diabetologist at my last visit about HbA1c values and complications. She told me that there is little evidence to suggest that an HbA1c in the low 50's would cause more complications/greater liklihood of complications than an HbA1c in the low 40's. Basically, the difference is negligible. But, she did say that you would be three times more likely to suffer recurring bouts of hypoglycemia with an HbA1c in the 40's. Apologies if I'm misquoting you Doc!
What I took from that is that creeping your HbA1c closer to 50 will not cause you much more issues than busting a gut to keep your HbA1c super-low. With a higher HbA1c there is more room to relax and not worry about dropping low which in itself, is enough to make the quality of life much greater.
