I’ve read some of the Polyphasic Society’s website, and they make a different argument. Unfortunately it doesn’t seem the website exists any longer (or now it’s at a different location?), but the Internet Archive has the page I read. You can see that they claim something a little more sophisticated than that they go straight into REM (with the implication that REM is all you need, etc.). Likely, they do this because the REM claims are false for multiple reasons. I discussed this with ChristianKI on LessWrong a year ago. Beyond the REM claims, their newer claims are contradicted by the research in Stampi’s book (see the link in the previous sentence for justification).
The reason you don’t see studies about polyphasic schedules like Uberman and Everyman is probably because sleep researchers consider the idea to be so far-fetched that it’s not worth doing a study. I have seen some polyphasic sleep proponents use Zeo, however. Look at the Polyphasic Society link I gave in the previous paragraph for an example.
