I think that's right. They take the highest percentage in any given county as the max. Then they subdivide somehow. It looks like the top range is about 50% of the maximum, then it's 25-50%, then 10-25%, and then 0-10 (or zero). But it doesn't look like the formula is consistent, although it's close, which suggests it's based on some sort of distribution. For example, perhaps it's quintiles (or quartiles). I.e., the first level of shading is for counties in the bottom 25% of percentage, then 25-50,50-75, and 75-100. Just a guess.
