Casual rank calculation


does anybody know how the casual rank is calculated? Is it possible the rank can be stuck?

I play few matches a week, I guess 2/3 are won, yet I have only one star and one chevron. In January and February I played more and have more chevrons… The result is that people think I am a noob and noobs hates me because I am better…

Can anybody help me to get at least two stars? :slight_smile:
