I subscribe to a non-scientific personal theory that the more haemoglobin we carry in our red blood cells, the higher our HbA1c will be. The HbA1c measure the glucose in the haemoglobin. The more haemoglobin we have, the more glucose will be able to bind to it. And vice versa.
When we have a full blood count the amounts of red blood cells, and the amounts of haemoglobin are counted. RBC is the number of red blood cells. MCH is the amount of haemoglobin. (MCH = mean corpuscular haemoglobin). My MCH has always teetered on the edge of the higher range, most often just over it. I blame this for my much higher than expected HbA1c results compared with rigorous finger prick testing and wearing a Libre sensor. My current HbA1c is 42, equated to an average of 7mmol/l. As I hardly ever see 7s - maybe once a week I may see up to 7.5 for half an hour after my Sunday roast - I cannot comprehend how this can create an average of 7. This is why I blame my MCH values and the large amount of haemoglobin I carry in my red blood cells. By the way, all other blood counts are bang on normal, and my meter is plasma blood calibrated, so the readings are equivalent to any plasma tests.
Your theory also holds true. If you have spikes to 10 sometimes, but spend much of the rest of the time in the 5s, those spikes will cause a lot of glucose to stick to your haemoglobin and it stays there. It doesn't fall off simply because there are mostly 5s. The lower readings don't negate the few high ones.
