Been using this for a couple of months now and recently I’ve had idd Hba1c predictions. When I switch it on it might say 41.6 but when I put in (what I consider to be higher readings than I’d like) it goes down to 37.7 (for example). Anyone else has this as its always a bit of a shock when it switches it on but not sure which reading to believe. I should add that I know it’s just a guide and not to be relied upon but odd it switch when I add high readings. Many thanks x
