Polyphasic sleep is based in maximizing the amount of time sleeping in REM cycles, which is supposed to be the phase of sleep when the benefits of sleeping are higher. Monophasic sleep deprivation doesn't have as many cycles of REM sleep as polyphasic sleep, given equals amounts of time slept. To compare monophasic and polyphasic a study should include both types of sleepers. Perhaps such study could find a proper pool of candidates in forums like http://groups.google.com/group/polyphasic http://groups.google.com/group/polyphasic
