If you’d like to hear the man himself talk about his history with matchmaking/ranking systems, career, and details about the evolution of Halo 5’s systems, I highly recommend checking out Episode 8 of HCS Weekly (link below). It’s hosted by theShyWay and is a great listen.
A couple good takeaways:- Don’t connect too directly your performance in your most recent game and how your CSR changed after that game. CSR is working towards MMR, it reflects previous games as well. - MMR can go up even in a loss, keep playing well and it’ll pan out in the end.Enjoy the episode, y’all.
