The ranked system finally figured out where I belong, but only sort of

Okay, I'm currently bronze 2. Please don't rank shame me, I'm aware that I'm bad at the game. I've been climbing steadily from Iron 4 this season, and I'm finally stopped climbing, but I'm not staying in the same rank. The thing that's happening is I'll often go on a winning streak and climb to bronze 1, then immediately go on a losing streak and demote back to bronze 2. This has happened a few times, and the emotional whiplash of promoting and demoting so quickly isn't great, haha I don't know what I'd suggest to fix this, if anything, it's just something I thought was of note, since I thought once you found your rank you'd stay there for a while.
