I'm getting less LP per win after 7 wins in a row
I was getting 22lp(-15 per loss) per game at plat 2 22lp, then I won 7 games in a row which got me to plat 1. Now I'm getting 20 lp per win and 16per loss. Which means my MMR tanked after 7 wins in a row? I checked that the average tier of the matches I won after I got to plat 1 is plat 1. I feel like the MMR system is not working properly.
