User blog comment:Commander Marko/Do Ranked KDA stats mean that much?/@comment-4888212-20140608225453

correction: KDA does not matter until you do not have a significant number of games to ramp up a statistic.

as long as one great/bad game can significantly change your KDA by more than ~0.2, the number of games were not significant enough.

TLDR: you cant make up statistics from 3 games.
