It would be hard to quantify, but it could be done There are different arguments for "Folks should be allowed more time off, e.g. walk the dog" and "Folks can multi-task while working, e.g. walk the dog and talk on conference calls." My argument (and I think your comment) was related to the latter, that human beings are more likely to overestimate their productivity, which various studies have shown.
