Me a player hardstuck gold, getting 16 points a game and losing 26, has recently found a way to increase my hidden MMR from gaining 16 a game to 28 and from losing 26 a game to only 15-18.

I decided to play some unranked games as I was really fed up with competitive being match mvp 4/5 games to get a measly +16 RR. I won around 20 unranked matches in a row now, over the course of 3 days and found that my opponents were also slowly getting better like ranked the more I won.

I returned to ranked mode today and in 10 games I went from Gold 3 to Plat 3 and am almost d1 now, I lost 1 game which deducted 15 RR compared to the 27 I usually lose. Getting way more points a game now and am 100% sure hidden MMR is linked to how well you did and won in unranked games.

Good luck to everyone grinding this act and I hope you try this method out, to anyone who has done this has it also worked for you?
