Well done dobber! 8)
You have achieved a LOT, but not yet non diabetic levels. That would be between about 3.5% and 5.5% with an average at 5.1%. A non-diabetic at 6.2% is most unlikely
I'm not trying to belittle your achievement, but trying to show you the truth. You have done brilliantly. The majority of diabetics never get that low. In my PCT area, fewer than half get down to 7.5%.
