But dang. Just came out of 2 hour warm-up with a reading of 204. Knew it was wrong–I almost always have to do a calibration at the start of a session–but that’s way wrong compared to usual with a 12-hr presoak. Only I couldn’t get to my meter right away and by the time I did CIQ had helpfully provided me with a 6 unit correction. Which I’m so thrilled about because my meter-tested BG was ACTUALLY 140, which is normal for me this time of morning after my usual coffee. So 6 units on board for kinda nothing. I know, I know, eat carbs, keep an eye on it. But I’ve been doing restricted carbs recently, actually helping take off some weight, and I was planning on going for a bike ride which, with that much IOB, would be a disaster. Crap.
Yeah, one of the nice things about the G7 is you have a 12-hour grace period at the end of the session, and you can insert your next sensor 20 minutes before the current one expires. That way you have no gaps in data!
I’ve switched to a G7 at this point, but I understand where you’re coming from. I’ve made it a point to start a new sensor on my phone 10+ hours after installing it and at least a half hour before the previous sensor expires so I can check it against my BG meter and possibly calibrate it before I let it talk to my pump. It hasn’t always fully settled down at that time, but it’s better than having the pump respond to completely wrong values (again).
Where I still have an issue is compression lows. If I roll onto my CGM at night or sit in a set with a stiff back that pushes against a sensor on the back of my arm, the CGM will drop 20 to 50 mg/dl in 5 or 10 minutes. CIQ will respond to this by shutting of my basal insulin. Then a low BG alarm goes off and I shift position, the CGM rises just as fast it fell, and CIQ will respond with a bolus equal to 2 or 3 hours of basal insulin, even though my BG is unchanged from 10 to 20 minutes earlier. I’ve had this screw up exercise plans but have found that using the Tslim sleep activity 24 hours a day prevents CIQ from doing this.
