Ummm....I think I'm going to disagree.

That's why it's a peer-review forum though, right?
I think you can most likely safely be shooting on those evening PMPS numbers. And doing that
should help to bring down the AMPS numbers as well. When you've skipped, the mid-cycle +3 numbers show a rise which means she still needs insulin, and that you could probably give a small dose on those blues and be okay. Of course if you decide to do that, you'll need to monitor to be safe, but you do that consistently anyway.
Lowering the AM dose will make the PMPS a more comfortable number to shoot, but it will also leave her in higher numbers during the AM cycle.
So I think I would leave the AMPS at 0.4, and try shooting 0.2 on those PMPS blues. If that goes well, you might even be able to give a bit more for the PM cycle and start to bring the AMPS into lower ranges as well.
This is a more aggressive dosing suggestion, so it doesn't hurt my feelings if you want to ignore it

. You could always try the reduction for a few days and see how it goes, and revisit this if you don't see the results you're wanting.
