[2021] Promoted from Gold 1 to Gold 3 on +29 RR win? - Confused on the RR system

Hey All,

I recently came back to Valorant after an extended break. I played extensively in the Beta (Immortal) and a little in Episode 1, Act 2 (Diamond 2 or 3, don't remember where I ended at this exact moment). I came back with the new Act that just launched and placed in Gold 1 playing against Gold 3-Diamond 1 players. That's fine, as I haven't played in awhile and I figured I'd need to rank up again anyways.

However, I'm confused on my last game and promotion. I was sitting at 86 RR in Gold 1, won a game fairly handedly against plat players, won 29 RR, and somehow ended up Gold 3 with 15 RR. Am I missing something about a mechanic that allows me to skip an entire rank because of my high MMR? I even logged out and logged back in to verify I wasn't actually in Gold 2 with 15 RR.

I know that with the previous rank system you could jump around drastically, but with the RR system, I didn't think this was possible. Anyone want to enlighten this confused player on the new RR system or is what just happened not normal?
