I have experimented for a week with the new settings. Thus far, I have managed without any corrections by eating fewer carbs, but have kept the carb/insulin ratios the same. That has cut the time that the pump is in suspension by one third. However, since the pump has the facility to suspend insulin, it would make my life easier to let suspensions happen. Unfortunately, the target range in my pump is set between 3.9-10 mmol/L, whereas I would prefer the upper limit to be 8 mmol/L. Anyhow, the DSN wants to see two-weeks data by the second week of August, so I can work on this more, but I would prefer to use corrections to keep readings below 10.
The pump suspends insulin before a hypo happens, so my reading very rarely go below 4.
