I'm polyphasic on Everyman 3 since about March 2011 (Jan and Feb spent unsuccessfully trying to make Uberman work). According to my aging Zeo I get approximately the same REM and SWS as I did on 7.4hrs of monophasic sleep before I adapted. Nearly all of the SWS is in my 3hr core. On Uberman I never achieved enough SWS in my naps to get me through. The adaptation was ridiculously hard - both for how very unpleasant it was and for having to get through that while sleep deprived.
I could believe that a 3 hour core could contain a lot of SWS, making it definitely better than Uberman. In those little naps, it's easy to jump into REM and hard to jump into SWS. I was under the impression that 3 hours is still less SWS than the minimum to prevent sleep deprivation symptoms, but I also am endlessly impressed by the capacity of the human brain to adapt to any symptom. Did you do any cognitive functioning tests before/after switching to Everyman?
Also consider how different humans are. Even the recommended sleep ranges have a spread of almost x2 between min and max.

Oh dear. Can we please not post very large very bright low-information-density infographics right into threads?
sorry. didn't find a way to rescale and forgot.
