even if you take the worst 4 maps from every player in the tournament he ties for 3rd to last at 31 kills, ahead of only boaster at 21 (who played 19 maps so this comparison is wildly unfair, is the best igl in the world and doesnt play duelist) and narrowly ahead of johnqt at 29 (who igls and doesnt play duelist). normally outliers should count for next to nothing. this is just an absurdly bad performance that it still has to count for something.
also "bringing down the avg by a lot" doesn't make any sense. if he played 1000 maps with the same shitty performances his rating still wouldve been shit. his stats are horrendous bc his performance was horrendous. simple as that.
