Hi @chris85 type 1
I think the US guidelines are a little different. I know retiring for me helped improve my numbers, but along the line so did prebolusing, a pump and a CGM.
In the US if you go by numbers they prefer you to be optimally 42-48 (6-6.5), but under 53 (7) has been the rule of thumb. With under 58 (7.5) if you are an elder. And a higher A1C is accepted for kids and for teens.
They used to have a fit if you were under 42 because they thought that meant you were having a lot of lows to get that average. But with the wide use of CGM's here they have learned to look at TIR more to show how you are getting to those numbers. They want you to be 70% TIR between 3.9-10. (70-180). They have figured out you could have a good A1C because of a lot of highs and lows which is not the healthy way to achieve it.

- Glucose goals can vary for each person, but a typical target glucose range is from 70 to 180 mg/dL. (3.9-10 mmol)
- For most people with type 1 or type 2 diabetes, a TIR above 70% is recommended. That's about 17 hours of a 24-hour day.
- You should aim to spend less than 4% (58 minutes) below 70 mg/dL, (3.9mmol) less than 1% (14 minutes) below 54 mg/dL, (3.mmol) less than 25% (6 hours) above 180 mg/dL, (10mmol)
- and less than 5% (1 hour, 12 minutes) above 250 mg/dL. (13.9mmol)
- TIR targets can be lower for older or high-risk individuals and for those younger than age 25.

Time-In-Range and Diabetes
Time-in-Range, or TIR, is the amount of time those with diabetes spend with their blood glucose levels in a recommended target range and is represented as a percentage. It is recommended for most people with diabetes to target blood glucose levels between 70 and 180 mg/dL.
