This jives with my personal observations of my work. I'm a very busy guy, but I easily spend 40% of my day not focusing on work. Probably another 20% is walking around talking to the people. To me, "focusing" on random stuff (ie. Hacker News, the newspaper, work-related or personal research) and completing tasks with minimal time is the best way to get things done -- the pressure helps me cut to the essence of whatever I need to do.
