People need fun. It makes them feel better. People who feel better work better and are more productive. I wouldn't be surprised at all to find out that an extra day of fun makes the four days more productive than the five days of work.

I believe the proper metric should be "profitability delivered per # of hours". If I can be more profitable, in less time, that should be more valuable than how many hours as a whole I've worked.
