I’ve been experimenting with xDrip+ combined with the Libre. Yesterday evening I calibrated once, at about 91 mg/dL. This morning BG meter said 96 mg/dL, but xDrip said 107 mg/dL. I recalibrated. Later today, I ate some pie, bolused for it etc. BG meter said 119 mg/dL, xDrip said 100 mg/dL. I recalibrated again. Now, a few hours later, BG meter says 97 mg/dL, xDrip says 109 mg/dL.
Now, I know that calibrating too often can be detrimental to the measurement quality. But, since I just started it, I figured I need to accumulate data points, so I calibrated more often to get a more robust calibration graph in xDrip. But now I am left wondering what tolerance range I should apply. I mean, up to how many mg/dL difference would you tolerate, and when would you consider it too far apart and in need of another calibration? 100<->119 , is this still okay for example?
