What is the number displayed on the upper left-handed part of the Sleep Analysis page?

This number represents the sleep score based on the duration of sleep and deep sleep.

The rating score goes from 1 to 100, and it is the following:

1 - 40 = Bad
40 - 60 = Normal
60 - 80 = Good
80 - 100 = Excellent

Please note: Age and gender may influence the sleep score result.
I think my Sleep Analysis registered an inaccurate fall asleep time; how can I report it?
