Might be an LP gain issue or is there something I'm not seeing.

Ok. I made a post about the same thing super recently, but now it's just boggling my mind. How the hell am I gaining only 16 or 17 lp per win, and losing 18 per loss. It doesn't seem to matter about win streaks or loss streaks because I've won 22 out of my last 30 Ranked Solo games. Can someone please tell me what's going on?

Someone, please explain this. And don't give me the "LP doesn't matter. It's the MMR that is good," excuse. I know it technically doesn't matter, but I could be around mid-Gold 1 by now, but the LP hasn't been in my favor. I'm salty, and I'll probably get over it soon, but I'm currently confused.
