-=== Sleep Regularity Index
-https://sleep.urbandroid.org/sleep-regularity-index/[SRI] is a metric calculated as the probability of an individual being in the same state (asleep or awake) at any two time points 24 hours apart (range 0–100, with 100 being perfectly regular).

 It is accounting for awakes, naps, and works well even for polyphasic sleep patterns.
 
 This index can be used for monitoring your risk of health issues - read about the link  https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10153326/[between SRI and mortality], the link https://www.nature.com/articles/s41598-017-03171-4[between SRI and academic performance].
