Some 15 years ago, when I was a software developer, most of the "problem resolution" situations happened outside the office when we were not thinking exclusively on the problem itself. In some occasions, in the end of a very busy day, we would leave the office an hour earlier to give us more "off-time" to let the ideas flow in. I think that pushing those over 100 hours a week worked in the beginning of industrialization where, really, more hours meant more products shipped. In our times, times of creativity, logging hours is irrelevant to productivity in general.
