It sounds like a fun experiment, but hard to control for the fact that your decisions, your "effective IQ", etc. are all greatly affected by being tired. This would let you do more stuff, but you were doing it all sub-optimally.

I agree, if I'm low on sleep I'm lucky if I can get through email, much less write anything coherent. If I'm not traveling I can usually get a full night and be fine during the day, but sometimes I still overdo lunch (I love food) and shut down in the afternoon.
