You can only go to an: I:C of 1:160 ISF of 1:600 ( if my kiddo was 350 with a target of 150 that would be .30, which is exactly what I have corrected with and had an am # of 98, but was that my insulin or her own?))) Target of 60-250: +/- 50 ( which is totally a flaw, you should not be able to target to a BG of 10!!!!) Basal of 0.025 (24hr total of .60 units, but you can set a 0.0 basal on the Ping) I know those numbers are just crazy, But with my dd that we caught super early and may start to bolus corrections and carbs, I found it interesting to see what the highest I could go was. Especially since we have two one the same pump! Although we do have each kiddos gear decked out with either Leopard or Gummy bear duck tape!!!
