I’ve asked around and found a couple of explanations for this. It seems that there is a carb duration setting in the meter, and I’d entered a snack earlier in the morning (just for future reference in case I wondered about my prelunch bg) but hadn’t taken any insulin for it. Apparently the meter doesn’t correct for the part of bg it thinks is due to the rise from the carbs you’ve eaten, which may be why it’s not been giving a correction on those occasions.
I also wonder if when you are within the target range it rounds the insulin dose towards the midpoint but doesn’t really add a correction as such. Not sure on that but seems to be what happens, I’ve changed the target range from 4-8 to 5-7, in case this is the case, as I have a half unit pen and use 1u drops 2.
Next difficulty is getting my strips changed. The dsn gave me 40 initially last Tuesday but I’ve run out of these now and haven’t got them on my repeat prescription list yet, though my old ones have been removed. So I’ve been to the GPS today to chase these and was told it’s waiting for change in prescription to be approved by a dr, so someone is going to ask my GP if he can do these since I’ve run out. I’ve got some old strips so I’ll stick to those for now. (If anyone needs a spare contour next one meter I’ve got 3 plus a few strips!). Next battle will be getting enough strips, as usually whenever I change brand they get put back to 50 instead of 200...
I also rang accu chek to ask about the software, they’re sending me a cable and a software disc (not sure why this isn’t online download...). Understand previous comments that it isn’t very easy to use or interpret but figured it was worth a look anyway given it’s free.
