I was under the impression that the Libre had to be within the same tolerances. So isn't it fair to assume that it is just as accurate as the meter?
Also, don't meters vary? I use an Accu-Chek Mobile for convenience but my DSN tells me that they are one of the least accurate.
Sorry this is complex, but people oten claim it is not! I expect you never studies stats to at least A level, and also you don't know the difference between "accurate" and "repeatable" when doing scientific experiments.
https://en.wikipedia.org/wiki/Accuracy_and_precision explains some of the maths behind it.
Both meters and the Libre keep to the same
standard for "accurate", but a meter is often more "accurate" then the standard says it has to be. The standard does not cover "repeatable". Remember that even how quickly someone puts the top back on the test strip container can effect both "accurate" and "repeatable"! And in the real would no one washes and dries their hands in the correct way before using a meter.
Given the option between a Libre and a meter to make life and death chooses
based on a single reading I know what I would choose, however my choose would not be the same if I wished to investage how to imporve my BG control...... (Libre has the great advanage of telling you the direction your BG is moving in that is often more useful then knowing the value itsself unless the value is very low.)
