Wow, I just wrote a reply and realised I'm still not sure as to the nature of the question.
What I would say, though, is assuming you are planning to nap before core sleep i.e Monday evening nap, Tuesday morning core sleep would be your "monday sleeping pattern" (I don't count it as Tuesday until I've had core sleep and that goes for any activities I happen to do on Monday nights etc). I would make sure there is at least 5 hours between the nap and sleep; or the patter is becoming close to monophasic. Plus, 4 hours or less in between is, in my opinion, slightly pointless. It's fine for polyphasic because it's a consistent 4 hour waking time. Splitting it 4 : 15.5 or 4 : 14 is probably too weighted one side.
However, I don't see a problem in making your "monday evening" nap alot earlier or "Tuesday morning" sleep later (e.g 4-7: I was tempted by this - 4am, 5am, 6am are the most unused and least productive waking hours for me. Period) if that's what you're implying you want to do? I know your schedule won't allow it, but I don't see a problem with even splitting your sleep equidistantly throughout the day. Perhaps two sets of 3 hours would be a more effective option there though.  |
