Agreed, with the caveat that HbA1c is unreliable in anaemia, haemoglobinopathies and recent blood loss, all of which are commoner than people assume. If it disagrees with fasting glucose or a CGM, that is worth chasing.

Worth separating that from glycaemic control, which this thread keeps folding into the same question. They behave differently and the advice does not transfer.

I read this differently. The confidence in this thread is running ahead of the evidence, and I would rather the uncertainty were stated than smoothed over because it is unsatisfying.

Agreed, with the usual condition: that holds for the average and this board is a collection of individuals. A population claim and a personal prediction are different things and get quoted interchangeably.

This is exactly what I could not find anywhere else. I will report back once I have actually tried it.
