Formulas used in calculating the sleep score.

Component 3 Sleep Duration		Component 4 Habitual Sleep Efficiency		Component 5 - Sleep Disturbances
				Interruptions		Feel too cold		Feel too hot
				Response	Score	Response	Score	Response	Score
		$\frac{\text{duration in sleep}}{\text{total duration}}\times 100$		0 interruptions	0	65 > avg	+1	72 < avg	+1
				1 interruptions	1	65 > high	+1	72 < high	+1
				2 interruptions	2	65 > low	+1	72 < low	+1
				> 3 interruptions	3
