Depends on the ratings that your opponents had. If you lose 30 times against teams that are 200-300 rating lower then you you lose a lot of points. And if you online win on teams that are 200-300 rating lower then you, you don't get a lot of points.

But i've always found it strange aswell. I had 1500 rating some seasons ago and had like 120-105. And some teams had 2000 rating and had like 65-25.

Kind regards,
