Great results so far! To a degree, the lower the better, but you can get fixated on this if you're not careful. In general terms, lower than 7.8 after eating is accepted by many as the target to go for to avoid complications as much as possible. I aim to always be below 7 after eating, and only occasionally miss (that I know of!) Vast majority of diabetics are below 6.5 two hours after eating, and most are below 5.5; most of the time when I do test I'm below 6.5 which is my real personal target. This has given me a latest HbA1c of 5.7% which I'm comfortable with. You need to find a figure which you're comfortable with, which also gives you the results you want with an acceptable (to you) diet.It's all about balance. Sounds to me as if you're about there!
