    The result is that on a hardness scale ranging, for example, from zero to 60, we allow for +3 to -2 points, a total range of 5 points; and if the hardness being measured is above 60, we use the reverse. In that case, our acceptance criteria are -3 to +2 points. That's still a range of 5 points on the hardness scale.
