There's lots of data supporting this, sleep research has gotten big in the last 50 years. I haven't studied the rationale behind the polyphasic sleep system but it sounds like a couple slip-ups and you're hosed, whereas if most people go without much sleep for a few nights they'll be tired but able to rebound with a regular night's sleep. It sounds dangerous to leave yourself constantly on the verge of sleep deprivation.
