    Is this true with Libre 2?
    I understood, the Libre 2 does a pretty good job of predicting the 20 minute delay (unless you trend changes direction in that period).

    Yeah, the "unless your trend changes", I've certainly seen evidence of based on Blood Sugar readings and 'general feel'. For instance, Fiasp (because of its speed) can frequently make the reader think I'm going Low when I'm not.

    Edit: Oh and taking Dextrose makes the reader freak out (in a way Libre 1 did not, to the same degree).

    I feel you've forgotten the BG meter has a lag of upto 20 minutes taking a "snapshot in time" at that point.
    But i would agree the L2 does a reasonable job at working out where we are "now."
