How Ranked is calculated for low MMR
If you were recently ranked this season and got a much lower rank than expected, you are not alone. I have figured out the equation RIOT uses to give you a rank after promos. (Applies for most players but more frequently for low MMR)
Silver II last season:
Wins: 7 Lose: 3
7-3= Bronze IV
Gold V last season: (this is a little more tricky)
Wins: 10 Lose: 0
10-0
1Ø-Ø =Bronze I
As surprising as it may be, with evidence, this is actually how my friend and I were ranked this season :D
