That “convenience comparison test” is a great idea!
FYI I started this week on the Abbott Freestyle Libre “CGM” for a 30 day trial run and am tracking it against a Dexcom G5 and my Contour Next One meter. The Freestyle Libre also has a built in BG meter BG using Freestyle Precision Neo strips. From a convenience perspective, using these strips will allow untethering from the separate BG meter and only carrying one device if I stick with the Libre. I like how the Freestyle strips are in foil packets that can be more easily packed in a side pouch of a carrying case compared to multiple round strip jars; I find the Contour strip jar to be a little too wide mouthed some times especially when I am packing 1 or 2 spare jars.
Since I don’t think this BG meter component of the Libre has been tested in any of the articles I have seen, I obtained some freestyle Libre test strips (Precision Neo strips) and will be comparing it against a Contour Next One.
As a general comment I have started thinking about the big picture for meter use and reminding myself that if I am over 200 it does not really matter if the meter reads 205 or 220, they are both too high. Once I get a high BG I am in trial and error mode with bolus to bring it back down. Similarly if I am trending low at 50 or 55 the precise BG number is not as important as getting some carbs. So I am not getting too hung up on meter accuracy at high or low BG levels as long as they are within about 5-10% of each other on average.
