Recently I've been viewing the leaderboards and I saw that [this guy](http://battlelog.battlefield.com/bf3/soldier/farhad_rus/stats/778604518/) has the highest **K/D Ratio**(***64.76***). But then I've found [another guy](http://battlelog.battlefield.com/bf3/soldier/Stationary-AA/stats/513908734/) whose ratio is even better(***477.25!!!***).

So I've got that question: what are the requirements to get to the leaderboards? Do you have to have a minimum of some amount of deaths or do they just ignore people with some crazy stats?
