Quackery. Realistically, you can only trick circadian rhythms for limited periods of time before they start fucking with you. Unless you absolutely have no choice, let your body naturally cycle through all of the sleep phases. Unless you're in a situation where small bursts of sleep will benefit you (you're in danger of a predator eating you), cycling through all of the stages is better. Polyphasic sleep gives you more total awake time, but at a much lower quality.
