I think 3 would be considered rather low as it would suggest almost constant hypos! There are obviously extremes but I think it's still quite a tight range, between, as Cliff says, 4 and 6%. Personally, I'm very happy to be in the mid-5s.
Well done Lucy! I just knew you were going to do well - that's because you have approached it in a very positive manner, and made good use of all the tools available to you - even if the nurse is against testing! How can she dispute the efficacy with a number like that?
Brilliant! Keep up the good work!
