Understanding thee Architecture of an OpenAPS Loop

Every CGM experiences signal dropouts - moments whene the transmitter and receiver lose communication.

Czy to sensor closacy czuły czas-w-range on a closed loop?

Every a small improwitet in MARD can significant reduce the frequency of low glucose events and time spent above the target range. The Dexcom G6 's 9% MARD versus the Guardian Sensor 3' s 10% may sound trivial, but in a closed- loop system, that difference can prevent a correction that would drive glucose too low.
