Most recently against Hammarby, Vittsjö decided in extra time and won 1-0.
At home against Kristianstad, it was not quite as successful, but at the back they nailed the store again.
Goalkeeper Sabrina D´Angelo and company have now only conceded nine goals in 12 games in the series and have kept a clean sheet in five games.
Only the top duo Häcken and Rosengård have conceded fewer goals than Vittsjö so far in the damallsvenskan.
For top-chasing Kristianstad, it is the second straight match without a victory after this weekend's big loss against Häcken with 6-2.
