Pick up a metric ruler and look at it. There isn't really that much difference between 4.9 and 5.5. In English that is 1.93 inches and 2.17 inches. How can they be sure it is that accurate? So why do they say one is safe and one is life threatening? The only reason to wait is if you know you are going to die in 6 months or so anyway, so why go through OHS.
