This property contains eight levels, each defining a range of exposure duration:

- `durationScores[0]` when duration equals 0.
- `durationScores[1]` when duration <= 5.
- `durationScores[2]` when duration <= 10.
- `durationScores[3]` when duration <= 15.
- `durationScores[4]` when duration <= 20.
- `durationScores[5]` when duration <= 25.
- `durationScores[6]` when duration <= 30.
- `durationScores[7]` when duration  > 30.
