This uses the lower bound of a 95% confidence interval for a Bernoulli parameter. (Read: Statistics voodo)
This tends to give a more reasonable sorting as it factors in the amount of games played.

# Example:

The first picture is ranked third because of the high amount of games played and a generally high win ratio. Even though the second picture has a much higher win ratio, the amount of games played makes the system less confident. (The value between the parentheses is the confidence)
