KRACH ratings 2012

In short, this system makes a set of rankings, where the ratio between the players' ranking are the ratio between the chances of them to win a set (I could use matches instead, but sets are better for that) in a direct confrontation.
A cutoff of 30 sets was used.
Many thanks to KleineBiere for giving me a file with all the matches

Re: KRACH ratings 2012

Now take another 30 sets for the same players and you'll have another ranking
Such system is good only when the players meet each other many times, not like in tennis...

A cutoff means that a player must play at least 30 sets - all results are taken into account.
