| I was able to get 5.5-6.5 a1cs on MDI. My highest was 7.1, and that is my highest ever. A lot of it also depends on things like activity level. I always noticed my highest a1cs when I wasn't very active (that applies to pump and MDI).
As for CGMS, it has not only been a convenience, but has revealed patterns in my BGs which I would have never discovered. I haven't had an a1c test since I began using it so I have yet to see if I have improved... it's hard to beat a 5.6. In my case I think it has been more a matter of stability.
