Haha, thanks for the warning. I am reminded of another time I ended up abusing the Landau notation in a numerical analysis class ( was it probability?) some years ago. The homework was to get and N^2log(N) algorithm of some kind, but I became concerned about certain large constant factors which I could determine exactly. However, these constant factor could be written as a series in another parameter, which I couldn't approximate in a certain limit and... well, you see where I'm going. There where lots of O's with slightly different semantics on the same paper.
