I think I figured it out! Those 4, 5, and 4.5g’s are insulin:carb ratios at different time settings? Sorry, the numbers are just smaller than I’m used to and didn’t recognize them as that. Either that, or I just need more sleep.
Yes, insulin:carb ratios are tied into timed slots in your basal profile(s). But, you can still easily accommodate what you’re used to. You just have to create a few more time segments.
00:00-4:30 1u/hr and 1:5g
4:30-6:00 1.5u/hr and 1:5g
6:00-10:30 1.5 u/hr and 1:4g
10:30-11:30 2.3u/hr and 1:4g
11:30-16:00 2.3u/hr and 1:4.5g
16:00-00:00 1.1u/hr and 1:4.5g
BUT… All that may not even be required. Most likely your settings are going to have to change. The pumps deliver insulin differently, their accuracies are different, and you’ll probably absorb the insulin differently. Fair warning, you may not be happy your first week or so. Growing pains. But once you get your new settings dialed in, you’ll probably find you can simplify them. Control-IQ is great at smoothing the inconsistencies out. You really just have to aim it in the right direction.
