≈ A sample of 165 parsed matches, not all of Dota: a hero needs at least 5 games to be listed (3 on one position), the numbers are rough until the sample grows. The rank is the average medal of the players of the match (≈, the season ranks STRATZ gives); a match with no ranks is only in All. The position is the one STRATZ gives for the player.
