Do you think playing with the food absorption rate can put the super bolus reaction into high gear?
So I don’t use Loop, but the food absorption rate, in my experience, is one of the more unpredictable of the variables. We’ve tweaked it because we found it decayed waaay too slowly when blood sugar wasn’t rising… but there also seem to be some glitches, at least in openAPS, where phantom carbs reappear after they should have decayed at the boundary points where ISF changes. Because the food absorption rate seems to have such an unpredictable effect on the temp basals, i really don’t play around with it too much. What I do to have a bigger superbolus is basically program a more conservative carbF into the pump than I typically use, then routinely bolus over what the bolus wizard recommends based on some internal idea of what the true carbF is, or even a little more. So pretty much immediately the algorithm will assume there’s too much insulin and shut off sooner. Though I believe that w/in the first 30 minutes after a meal bolus, it takes a pretty hard crash before the algorithm will set a zero temp basal.
Not using autotune. We use autosense, which modifies insulin sensitivities based on the past several hours, but I don’t think it makes a huge difference. We ran autotune a few times and the parameters it spat out were too different from what we were using and so we were reluctant to go with them. If his numbers were totally out of whack we might have been more willing to experiment, but given that it was a time when he was in reasonable control, didn’t seem worth it.
