Right, so the meter will try to correct you to 10 in the early hours and 5.5 the rest of the time, cos it goes for the middle of whatever range you enter, with 4 being the minimum number you are allowed to enter. The 10 is too high for starters.
And 5.5 as a daytime target is marginally on the low side IMHO, with long acting insulin floating about, but 4 is also too low as the bottom really, you'll have far better results to start with if you aimed for a midpoint of 7 and changed it to 6.0 to 8.0.
NB It doesn't actually use that 4 there in the Time Blocks, to understand when it has to tell you that you are hypo - it does that anyway below 4 every single time whatever it says in the time blocks.
You have to remember (if you ever knew this?) that your A1c will always be lower than your meter average so if you set the mid-range too low, you'll have a ridiculously low A1c, which wouldn't be healthy.
I know it sounds counter-intuitive but if you initially aim for a higher number and you can get that to even you out, then it will be comparatively easy to tweak that.
Having told the meter what you want to be, which is on the high side anyway - why aren't you taking it's advice? Except when you've had a lot of alcohol in the evening of course, and surely you don't have THAT much most nights? On the nights you do indulge you could just ignore the correction dose it comes up with, or halve it or something? Or would you typically actually be too hissed to be sensible about it? You have to learn to accept what it says and that can be hard, been there done that myself.
You don't appear to have answered the other question about what it would tell you if you entered an odd number of carbs, that doesn't work out to a whole number - does it round up/down or not?
