What this site is not
A short page, because the list of things this record cannot do is longer than the list of things it can, and leaving the first list implicit would be a way of borrowing authority the data has not earned.
Not a survey
Nine dwellings. They were not selected by any procedure that would make them representative of anything, no weighting has been applied, and no figure here is a share of any population.
A reader looking for a number that would recur in a tenth home will not find one. The method is published so that somebody can go and find out.
Not about health
Nothing on this site concerns anybody's physical condition, wellbeing or comfort in the ordinary sense of the word.
There is no field in the record from which such a claim could be derived. A short sitting is not evidence of discomfort and a long one is not evidence of its absence. If a page here appears to edge toward a statement of that kind, it has gone wrong, and it is not a statement the underlying log could support.
This site is not a source of medical, clinical or health information of any description, and no part of it should be read as one.
Not a recommendation
No product is named anywhere. No arrangement is called better than another. Nothing here is a suggestion about what to buy, and there is no affiliation with anybody who sells anything.
The one object the record counts — the seat — ended a sitting six times in forty-five person-days, and the page about it explains at length why that figure supports no conclusion in either direction.
Not a benchmark
The figures describe nine dwellings over forty-five days. They are not targets, they are not norms, and comparing a dwelling to them is a use the record does not support.
Not a judgement of anybody
Every dwelling in this study is in ordinary condition and was built for the ordinary assumption that it would be empty during the day. Nothing here says anybody designed, specified, let or furnished anything badly.
What changed is the use, not the buildings.
What it is
A count. Two hundred and twenty-five stretches of work, each with a place, a length and an ending, kept by nine households for a week each, with the instrument published in full and the open questions listed in the order somebody would attack them.
