FFA isn't rewarding me any csr

So I’ve been champion for a while in FFA. If I don’t play a while, I usually go down in rank a bit. But recently, I’ve been going up in rank, even though I haven’t played in like a week. I was champion 175, then I came back a few days later, and I was champion 172. I hopped into a game and came second place. I went from 172 clear down to 185. For SECOND. I thought that since a player had quit out of the game, maybe it screwed with the stats. So I played another, and came second again. No one quit, and I went down to 190. The next game I won, and I was still at 190, even though I beat another champion (who was higher ranked than me). I am currently at champion 195 with no desire to play more in fear of being bumped out of the champion rank. Why does this exist?
