how is MMR calculated?

i know how it works, i know that it affects your LP gains and losses, and i know that your MMR is based off your individual performance. but how is it calculated?

in ranked i usually only play support because it's easy as shit to climb with. but my stats will be a lot different than everyone else's on the team, i'm not farming, i'm aiming for assists over kills, and i probably won't do much damage. so what kind of stats is MMR calculated with?

i would assume KDA and kill participation over farm but i've seem some people say that their MMR is dropping because their farm is bad. how does the system detect whether or not you should be farming? i could be playing a really mediocre 30 farm leona top for all they know.

is it really that simple? i thought it was a complex algorithm of kda, farm, kill participation, objectives taken, carries babysat, etc etc. no wonder i have such a fucking high mmr even though i'm terrible.

Yep super simple. The game only matters who's nexus is standing. KDA only matters when you want to make excuses about why you didn't win (elo hell)

no no this isn't a whining about "elo hell" post i kno that's not a real thing. i was just wondering bc when me and my duo were climbing we were consistently matched against people in like G2-3 even though we were like silver 1 at the time.

Yes your mmr increases till you have a win loss record 50/50 essentially.

so what does it mean if your MMR is higher than 50%? does it keep increasing or is 50% the cap? mine is ~80% win, does that mean i have the same MMR as someone with a 50% winrate? i don't know why riot makes it so confusing lmao.
