Are there any guides/rules of thumb/formulae for the difference between I:C ratios someone might have?
I know there are for calculating ISF (i.e., dividing 1600, 1700, etc. by TDD) and know there are for calculating carb ratios, but is there any rule of thumb for how much two carb ratios would be expected to vary?
The reason I ask is that DD's breakfast carb ratio is 1:30, while all other meals and snacks are 1:50. The CDE mentioned that that seemed like a "big" difference. We suspect that it might be masking a basal issue. For now, DD is in school, what we have seems to be working, and weekends are different enough from school days not to provide a useful guide.
