I normally change mine at 14 days, so I can start my presoak on Saturday night, swap the transmitter on Sunday morning when I BG is nice and stable, and rinse/repeat.
If it was more stable like the G5 was for the first day, I wouldn’t mind starting new ones in the middle of the week. But even with the presoak, I like to have a non-work day for my first day on a new sensor.
