I started with Omnipod about 18 months ago. My last few years on MDI I developed pretty rotten DP and was usually 160-180 in the morning. Even if I used a small evening shot I would sometimes go to the 40s during the night. Sounds like you have one profile with two time segments on your PDM. My DE set my initial basal profile to .55 12am-4am, .60 for 4am-7pm, .55 for 7pm-12am. She felt the evening drop was important to counteract DP. That really worked for me as the DP disappeared almost immediately. A few months later I tweaked on my correction factor because it seemed if I went high the corrections were not strong enough. Neither my insulin or correction factors we’re adjusted in the first few months. We worked on confirming the basal settings first. I now have 2 stored basal profiles, a “high” and “low”, both use the same three segment time profile above but the high delivers more insulin. I use it for travel, cruises, days when I don’t have exact carb counts. When I stick to a steady plan I drop it to low.
So you might consider breaking into three instead of two time segments. I use .05 increments but I am on a concentrated insulin (off label for Omnipod actually but 25% of my DEs pod clients use it so I’m totally comfortable with that). The absolute numbers I use vs what you use don’t matter as .1 may be right on for you. When you are working on getting your basal rates right I strongly recommend that you use similar infusion sites, follow a steady meal plan, keep variables the same as much as you can so you can reliably see if the basal change you made worked or not. Also don’t over tweak by changing factors and basal rates and time blocks at the same time. I think my DE was right on in getting the basal rates nailed and then tweak the bolus factors. I checked in with her on changes I thought I needed. Omnipod is wide open to set whatever so just be methodical.
