Conflicting information from GP

I was diagnosed with T1 this January and I have had about 4 visits to the GP since then but since I live in a small town we have a different GP every week. This last meeting I had with one he was very annoyed at me that my blood sugar levels havn't been between 4-8mmol/L. Is this a realistic expectation from him? Keep in mind I've only had just on 6 months to get used to being diabetic.
