Well, I don't think that he is trying to get a solution, just something to evaluate, like you said it's not possible to solve an equation without having so many parts missing, however the more parts you have the more accurate guess or several guesses you can make.
I believe this is just non-sense anyways, like the theory about older accounts that should have some strange power against the banhammer.
Even tho this would make more sense, since it is about their income afterall.
