I like your approach here, but the numbers dont add up to the same number through time because
The data do not count sleep, or time with people who wouldn’t be categorized in any of the relationships shown. (ref).
The total hours in the data vary from 10.52 hours to 16.48.
“people who wouldn’t be categorized in any of the relationships shown” covers a wide swath of activities that we could probably have disagreements about. if I am alone at work where does that fall? If I am at work in a client’s office or building something at a client’s house are they a co-worker? if I am a senior in a nursing home with staff to help me, are those co-workers? Friends? Am I alone at the museum, when I am at the museum?
