Rating point calculation issue

Hello!
There is a problem with the calculation of rating points in case of victory. We are currently playing together with my friend on Bronze 5. For a long time I see the following tendency - when I win I get from 50 - 75 points on average, my friend gets 200-250. and this is very depressing. What does this have to do with it and is there any way to fix it?

That’s a feature in Bronze 5. Point gain resumes to 200+ when you get to Bronze 4 and above.
