1:5
1:4 for me
I’m somewhere between 1:20 and 1:24. Currently I’m at 1:23 for fun. I’ll start fine tuning my basals in about 2 weeks.
I’m at 1:5. I used this ratio with MDI and am still using it with the pod. I am still working with the doctor to tweak my settings so this may change. I’ve only been on the pod for three weeks and I love it despite all the lows I’ve been having as a result of tweaking too aggressively.
