colouring off-kilter with 20-80 rating scale

[Zeyes]

Not a huge problem, but the colours assigned to ratings are off by a few points on the 20-80 scale. In every other scale, the colours respect the scale's boundaries exactly. Here's what I mean...first, all the other rating scales. The numbers in brackets are the "native" 1-200 ratings visible in the editor:

1-5 scale:
red     1(1)    -  1(39)
orange  2(40)   -  2(79)
yellow  3(80)   -  3(119)
green   4(120)  -  4(159)
blue    5(160)  - 
 
1-10 scale:
red     1(1)    -  2(39)
orange  3(40)   -  4(79)
yellow  5(80)   -  6(119)
green   7(120)  -  8(159)
blue    9(160)  - 
 
1-20 scale:
red     1(1)    -  4(39)
orange  5(40)   -  8(79)
yellow  9(80)   -  12(119)
green   13(120) -  16(159)
blue    17(160) - 
 
1-100 scale:
red     1(1)    -  20(39)
orange  21(40)  -  40(79)
yellow  41(80)  -  60(119)
green   61(120) -  80(159)
blue    81(160) - 
 
2-8 scale:
red     2(1)    -  2(32)
orange  3(33)   -  4(98)
yellow  5(99)   -  5(131)
green   6(132)  -  7(197)
blue    8(198)  -

And now the 20-80 scale:

red     20(1)   -  30(41)
orange  35(42)  -  45(90)    [45 ends at 91 native points]
yellow  45(91)  -  60(140)   [50 begins at 92, 60 ends at 141 native points]
green   60(141) -  75(189)   [65 begins at 142, 75 ends at 191 native points]
blue    75(190) -            [80 begins at 192 native points]

In other words, ratings of 45, 60 and 75 can appear in two different colours depending on the underlying "real" rating, and I presume that's not intended.
