Besides the problems mentioned by others, doing the calculations with integer math (the FICS Elo calculation code is open source) means that for very large differences, any tiny gains are truncated. So for a huge difference you cannot gain points at all (rating = rating+.99 points => rating). It would have to be changed to floating point to fix it. It seems funny to do math using logs and exponentiation in integers only, doesn't it? Of course, no matter what you do, it is easy to manipulate the system for all sorts of false rankings.
