How big can the points difference be to still get points?

Just beat someone with 1000 points below me and didn't get a single point

I think it should be less than 400 points diff

i need urgent help
anyone here

Probably fractures of a point so you just see a rounded value which doesn’t change?

You always get rating... Just sometimes you get less than one full rating; Like +0.7 rating.
Example: If your rating was 1700.22, then you wouldn't complete the point with .7, and you would see: +-0.
But if your rating were 1700.30, then it would complete the rating point,, and it would show as: +1 rating...

@Purtzian I hope this was helpful!

Needless to say, your rating deviation coefficient is crucial. If you are new or restart old ratings you can get multiple times as much compared to established ratings
