I worked several years as a feelance audio engineer. When I started out I remember beeing concerned that I didn't have enough productive working hours. I found it hard to have more than 5 hours productive work done during an 8 hour work day. Also, since I was invoicing for the hours worked I felt that I should be far more efficient. After discussing this with other freelancers I found this to be quite common. Now, many years later, I consider 6 productive hours to be a really good day, and I will invoice it as 8 hours.

Today I manage a team of developers, and my experience is that the quality of the output is much better if they are focused and well rested, and that the amount of hours worked does not directly translate to better work. So if someone on the team is tired because of their kids not sleeping or something similar, I actually tell them sleep a few more hours. It seems counterintuitive, but I find it to work better for everyone on the team.
