Last act I peaked in D1, this act I got placed in silver 1 after winning only 1 of my placement games.

Last night I was Silver 1 50rr I played 2 games and did well in one and pretty mediocre in another I received 35 rr for the higher performance game and 33 for the mediocre game so 68 RR total. After getting out of the second game my rank is now Gold 1 with 18 rr. Where did Silver 2 and 3 go?

Edit: it sounds like I probably only skipped one rank and maybe not two, I have no idea.
