Yeah one of my professors had our class do an exercise on how we think presentations should be graded. He preferred a 5-level system because it gets harder to objectively define the difference between two adjacent levels when the increments are finer.
Which made sense, he wanted to be fair and objective. I think when you get into the “finer shades” as you say, one tends to rate based on comparison to other books too much. Like “A and B were both great, but I liked A just a teensy bit better, so I’ll rate them 9 and 8.5” Which is fine and all for your personal book ratings if that’s what you prefer. Not so great for students when you give one 90 and another 85 but can’t explain where the difference comes from.
