Or maybe a number ever closer to the Office Space number. I think I recall the main character saying that once all of the distractions, needless interactions with other employees, and 'spacing out' (I took that as low quality sleep with eyes open) were removed only about an hour of actual, real, work was being done.

Particularly for what are really creative arts, a more relaxed day and better quality of life /outside/ of work are probably important positively correlated factors in performance.
