I would be very worried that any increased accuracy requirements might translate into incresased prices for test strips. Already a lot of diabetics have trouble justifying costs of a couple tests a day.
It's important to me that I have strips for testing when I wake up, before I eat, before I drive, before exercise, before I go to bed, etc. I am not too worried about the difference between 90 and 100, but I do need to know if my bg is 40 or 90 or 190 before I drive the car or head out for exercise.
Anything we can do that would encourage competition and drive prices down, I'm all for! There probably is a market (accounting types) who care if their bg is 100 or 110. But I'm mostly looking to differentiate 40 from 80 from 120 from 180 from 240. Note those line up with the sticker on the side of the chemstrip bottle!
