Hate to break it to you big guy, but pretty much every system does this! This shocking reality is because the FDA only require a +/- 20% accuracy with strips. So if the ‘real’ sugar level is 200, then a reading of 160 is considered acceptably ‘accurate’ and so is a reading of 240 … according the the FDA! Same for One touch, Accucheck etc. They are all as weak as each other in that respect. Sick, huh?
