In your own experience does putting the new sensor on early (I assume you just leave the transmitter on the previous sensor until ready to swap) make a noticible difference? The reading from the first 8-16 hours of my new sensors are a total mess to the point that the readings are unusable — they jump all over the place from, e.g., 2.8 to 10 and back again (sometimes reading just ‘low’ without a number) in 5 minute intervals. Then after the 8-16 hours the readings suddenly become stable and pretty much match finger pricks. It just means that I really only get 9 days out of a sensor because the first up to 16 hours I finger prick because the readings are so random
