I vaguely recall reading a study about the optimum work week for thoughtworkers. I've often cursed myself for not keeping a link or reference around. Maybe someone else might help me find it? I think it was a german study. The conclusion was that 25h per week produced optimal results. The number might be a bit off but the idea is about right.

According to the latest official figures, 43% of all statistics are totally worthless.
