In some conditions, the maximum value in the map's data table can be one higher than the maximum allowed for in the key. See below:
In these cases, the color is still applied correctly - but it looks odd. I believe the problem is due to rounding the top value in a range down in all cases. I.e. quintile ranges are always rounded down (max value) or up (min value) so that the gaps between ranges are always different. At the top of the maximum range, however, if the value is say 845.9 the range will round down to 845 but the display will round up to 846.
