Sorry, just a pet peeve of mine.
Solved it by getting a Cal-king. Much happier, more snuggling with my wife, and my toes don't hold up the end of the blankets any more (I'm 6'2").
The only problem I've had since is that 4 Cal-king sheets we ordered in a row were mislabeled, and in fact Kings (or some other shape/size. trust me, they've been pretty weird). But that could be because I'm in the Midwest, where Cal-anything is mostly unheard of.
To get back on topic, the article is rather amusingly complete... I'm quite impressed someone would put this much work into this (though not surprised. A (math) geek, obsessed? never!).
We have tried to rotate the duvet and pillows to get the same effect, only to find The Boy's head at my feet next morning.
If you really want to rotate your mattress: IKEA used to sell round beds and mattresses. It's a bit too "Playboy Mansion" for my taste though, and it severely limits your options in sheets and duvet covers.
