The main problem is that... There are not a lot of studies on sleep deprivation, potential long-term effects. There is also almost no real studies done on polyphasic sleep.
A main issue I see this that a lot of scientists look at this and go "Yeah. That's obviously bullsoykaf. Too good to be true, etc." but won't actually look into it. (perhaps lack of interest?)
However, because there is little to no studies done on it, people are experimenting on themselves. Which is..good, but it's hard to prove or have conclusive data on it... I mean, it /is/ a blog.
I'm actually going to be starting up a study on myself..But honestly, it's not going to help out very much. My girlfriend (studying neuroscience) will be taking notes of my reactions and cognitive function. BUT this is one person being studied...and it's more for myself than anything else.
Also, to answer OP: Yes I am interested. super bump.
