Insulin to carb ratio

A lot of T1 diabetics will find that they are least sensitive to insulin first thing in the morning and more sensitive as the day goes on. My ratio is technically 1:12, but I just use 1:10 as on MDI, there is no way to discriminate between 1:12 and 1:10 unless you eat >50g in one go. Which reminds me, I should really get a half unit pen for that reason...

Anyway, I just use 1:10 throughout the whole day and I seem to be sound. I do go to about 1:20 for meals following fairly strenuous exercise, as the exercise makes me very sensitive to insulin but only for 4 hours or so after the activity.
I am the opposite! My morning ratio is 1:7, it gets longer as the day progresses. Any body else like me? Am I in a big minority?
 
I'm probably somewhere between 1:3 and 1:2 for those wondering if they are the only ones that don't meet what seems the impossible level of 1:10 or 1:12

And for people with insulin resistance, we can look at these numbers with wide wondering eyes. My ratio is about 5:1 in the morning, and gets bigger throughout the day. (Yes that IS 5:1, not 1:5. Five units of insulin per gram of carb.)
