I just played with the .1 setting (advantage of not being plumbed in yet) and it does work in a really weird way.

I told it to do a 5u combo bolus. I set it to 0% up front and 100% over the extend period. So logic would tell you that it puts it in gradually over the 6 mins.

Not so.

It whacked in the first 2.5 units immediately (4 seconds between each unit as I have it set to slow) then put in the other 2.5 units on the stroke of minute 3... What on earth is that all about? The only reason I can think of to do a .1 combo bolus is to combat issues like yours / stinging. In its current form, this feature appears useless...

For the sake of experimentation, I've just told it to do the same 5u bolus over 30 mins (the next timescale available after .1). Again, it was nothing up front and 100% over the extend period. It did nothing for 3 mins then put in a 0.5u bolus. Same at the 6th min. I am guessing it's going to do that for the rest, but I'm going to bed

I seem to recall reading that the 2020 puts in basal every 3 mins. I am guessing that 3 min delivery intervals is the best it can do, and it will put the 'extend' in within those 3 minute chunks. If I'm right on all the above then the best you can do is set delivery to 'slow' to get the 4 second gaps and do the .1 extend which will at least cut the bolus in half. Not ideal by a long shot, but the best you've got at present.

Gary, you found the flaw with the Animas. Yes, that is how it works which is in a sense useless. As far as I know all pumps give a basal every 3 minutes. So whatever one's basal rates are per hour it divides by 20 and gives that every 3 minutes.

What the Animas does is exactly as you described and gives it with the 3 minute incrememts. I'm sure a combo/extended/dual-wave on the MM and Cozmo would act in the same way.

The biggest feature I like with the Cozmo is that you tell it how long to give a bolus over and it does that evenly. That is really beneficial because then it's given over a period of time evenly and not all at once. You can set how long you want it to be set. The MM is set at just slow at I believe (without pulling out my manuals) at 1 or 1.5 units per minute.

Congratulations on getting your cholesterol levels down. I'm sorry you couldn't do the same with your A1c. Hopefully it will be lower the next time!

Kevin,

When I first replied I just assumed the 2020 would give that bolus evenly over six minutes. Thanks, Kevin, for doing the research.

Would it help to give your bolus over 30 mins., and maybe a little earlier before you eat? That would certainly give you a much smaller increment each time.

I've been doing that but the problem is there I go high faster and have to wait 30 minutes for the insulin to catch up since I do that maybe 5 minutes before I eat. I've tried doing it earlier and I just simply go low. That does work though for the most part besides sending me higher than normal to begin with.

Can you try changing your infusion set more often, or maybe a different kind? Are you rotating as much as possible- arms, butt, thighs, arms, etc?

Actually, MM uses a constant .05 delivery stroke, and varies the time between to calculate an extended or 'square' bolus. If I want to give 5 units over 30 minutes it uses 20 strokes per unit X 5 = 100 strokes. Every .3 minutes it will give a .05 delivery. If I want to give 5 units over an hour, it will give .05 units every .6 minutes. I agree that when doing a normal bolus, it has one speed, which is slow. It takes time for an extremely resistant type 2 using large amounts of insulin to give a meal bolus. For most type 1's this is not an issue.
