We had a deadline at work this week, and several times I stayed up late, writing code, trying to meet the deadline. So my sleep cycle was completely scrambled, last week and this week. I've been only partially catching up over the last 2 days.
I would think the average amount of sleep is less interesting than the variance people demonstrate, in their own lives, over the course of a month or a year.
