Work isn't always creative though is it? It's often more menial: meetings, learning new APIs, stepping through existing code, trial and error, mentoring, etc.

For these your ROI per hour goes down, but your total ROI still goes up even after 5 or even 8 hours. Maybe not for everyone everyday, but for some people some days for sure.

That's why I still believe in 8 hour working days. Three hours for meetings, reading up on things etc - five hours for the hard creative stuff.
