: In scientific studies, [SE]Polar is often compared against the "gold standard" of sleep measurement, Polysomnography (PSG) , to evaluate the accuracy of consumer-grade trackers.
The general formula used by these devices to determine the SE value is: [SE]Polar

Sleep Efficiency (SE) is a critical metric used to assess sleep quality. It is calculated as the ratio of total sleep time (TST) to the total time spent in bed, expressed as a percentage.
, comparative studies using Polar data may analyze it based on mean and standard deviation (SD) within specific study populations to identify "good" versus "poor" sleepers. Formula for Sleep Efficiency
