I suggest asking Insulet; they’ve been touting this for coming on four years now:

(The second bullet point on that page, but they media-blasted the work with Lilley the year before.)
If you run U100 for 1 to 1.5 days then U200 in the same device will run 2 to 3 days, but to make that happen you have to carefully go through every setting and divide, or multiply, by two, and you have to get it right. There’s no setting in the Dash PDM that I can see for setting the insulin strength, though I would guess there is a secret setting for doing so.
There’s no magic; it is just a wireless subcutaneous fluid delivery system. They train their own non-diabetic employees using saline solutions and the pod doesn’t stop working. I am slightly weirded out that it takes them 4 years not to get approval for U200 or U500 insulin.
Oh: update, here’s the FUD thread:
Also way old, but you’ve seen that one already.
