Hi, I am using the Omnipod Dash with humalog, which is a littlebit slower and which I take 15mn in advance before eating.
1) A profile Glucose change of 1-2 is not massive and is prefectly reasonable (my opinion).
But you repeat the Basal testing for several days to get a relyable and repeatable result. Also you may test part by part of tthe Basal-profile other parts (morning, night) in the same fashion. You may need quite some time to obtain a fairly stable Basal profile.
Also be aware that your Basal may change in time. I do have the problem for example that my need of Basal is changing of the year and the period maybe 2weeks up to 2-3 month periods by up to 30% up or down.
Essentially I have added several similar profiles with changing amount.
What I am doing if I recognise a change in the same direction in Basal (best seen over night) over 2-3 days I am starting to adapt to switch my profile, even adapt if necessary.
2) After all this you start to check for your carb/insulin ratio with some good known carb-intake over several days. Maybe you have also to differeniate over the day(Breakfast-time, lunch, diner and night) over several days. The same you may try to do with your correction ratios. But with this correction tests you should wait until you have no meal insulin in your body any more, which maybe more difficult to do.and may need some more guessing than real test-results
3)Anyhow, if you got through your testing and processing and rechecking from time to time you'll see in time what your glucose profile will tell you. For me I reached a reduction in my HBA1C reduction for around 30-40%.
Especially average and time in range and Hypo- and Hyper-timings will tell you.
For me the results was really great. But I must say I had the advantage that I worked for some month at home with fairly controlled conditions
Anyhow good luck.
PS: if you are reaching the end for a pod after 72h it'll continue for another 8h(as long there is enough insulin in the pod) before the final absolute stop of the pod. Even though the PDM is showing in between that your pod has expired. This may help you for work where its not always possible to change the pod directly.
