Battleground blitz problem

Hello.

Hello i just started with RBG blitz and I have problem with rating.

I played, won and got 192 rating.
After next win I stayed on 192, did not get 384.
Played few more games and I get 576 rating.

Today after win I did not get 768, the rating dropped to 192 again.
In stats I saw I played 3 games, but I played about 10.
