- The interval can be:
-- Rounded down: [x.00 .. x.25]
-- Half star:    [x.26 .. x.75]
-- Rounded up:   [x.76 .. x.99]

- down: with halfShow enabled, score <= x.25 will be rounded down; (inclusive)
- up: with halfShow enabled, score >= x.76 will be rounded up; (inclusive)
- down-up: with halfShow enabled, score > x.25 and score < .76 will be half star; (inclusive)
- full: with halfShow disabled, score >= x.6 will be rounded up; (inclusive)
