I've just had a go and came out at 14% which seems high for someone only recently diabetic and relatively fit etc. I think I'm with Helli on this one in that it feels quite a blunt tool bit like BMI . Does it assume that you're not managing your diabetes or does it take a 70% TIR as the baseline? My last two hospital consults I've been told very bluntly that I will get complications and I did wonder if that was true, based on old data or just an assumption that most people won't manage their condition that well? My numbers are much better than friends with type 2 who take a more relaxed approach but again no idea what that actually means? Is type 1 (as no box for type 3) inherently much worse?
