Given the percent of the map that falls in the 0-50 range, there’s really no reason for it to be 5 (or 10) colors. Conversely, the 90-100 range accounts for a very large amount of the map, and being able to differentiate it is valuable.
This isn’t like a graph where the scale changes in the middle to obfuscate the data; it’s making the map more readable and providing more information, it just requires the user to actually be literate.
I’m not trying to say anything against the map makers.
More pointing out how consistent the spread is. The vast majority of places have very similar values, between 80 and 95%.
0-50% is one color.
50-90% is 4 colors.
90-100% is 2 colors.
