Hi guys i have read a lot of post about mmr but im still not sure how it truly work is it only based on win and lost games or is it based on how you do in game i would like a detail explanation of how it works if someone has a bit of knowledge on mmr thanks
Well, generally speaking, it is supposed to be an indication of your skill, based on how you stack up to everyone else's MMR that you play games with. If you play games against people of a much higher MMR, you will lose less MMR for losing to them, but more MMR for winning against them. For people with similar MMR's, you'll gain and lose about the same amount when you win or lose the game, respectively.
We don't know the actual formula for calculating MMR, but that's generally how it works, iirc. We don't know all of the details, but it appears that winning and losing and your opponent's MMR are mostly the only factors taken into account... at least, that we know of.
