A relatively good day on Loop.  Preschool probably mis-estimated the carbs for lunch (pasta).  The activity in the evening didn't drive him low.  Great.  I think the algorithm could be a bit better on the steep rise.

Changes to the algorithm today involve being a bit more aggressive with Bolus treatments:

  • Give 80% of required insulin as Bolus upfront
  • Allow a Bolus every 10 instead of 15 minutes
Also ran oref0-autotune out of curiosity, which kind of confirms our numbers:
