I suppose it depends on the type of work, but as a web developer I’d be very unsatisfied with my team if we only got 20 real hours of work. On my previous team we did pair programming and had a very sustainable 30-32 hours a week. Now this did include ~3 hours of meetings, but they were always productive, good meetings. Our trick was to work in 90-minute bursts, with 30 minute breaks where we actively stepped away, took a walk, played ping pong or Nintendo, got coffee, stretched, etc.
