Wanderer: You're very welcome! When you do your own polyphasic sleep adaptation, I would encourage you to also post a day-by-day log here. My hope is that by accumulating sleep logs from several different people, we gradually get a much clearer picture of how polyphasic works and how best to do the adaptation. Right now the waters are still very untested.
Mr. Punch: Don't forget the other variants: 4*30 is the one I'm using, and I suspect that 3*45 would also be feasible.
