   - doc: Stress levels are provided as 3-minute averages of the real-time stress scores generated on the device with values ranging from 1 to 100. A value of -1 means there was not enough data to detect stress, and -2 means there was too much motion (e.g. the user was walking or running). Scores between 1 and 25 are considered “rest” (i.e. not stressful), 26-50 as “low” stress, 51-75 “medium” stress, and 76- 100 as “high” stress. Usually assocaited with Stress Details Summary using the summaryId.
