No clue how that math called MMR works.
In normal I'm laning and winning against Gold 5s, in ranked I'm B3 :/
Normal MMR is separate from ranked MMR.
Can anyone explain to me how MMR is calculated? I won two games in a row as Garen (getting into Silver I), and getting S- and S in both games. Yet according to op.gg my MMR than proceeded to drop by 20 points...
Why?
A lot of the basis of your MMR can be judged on the ranks of the people your matched with. If your playing against people higher ranked then you then your MMR is believed to be higher. As such if your MMR is lower you will be paired up with lower ranks. Maybe you lost a bunch of games prior to winning those 2? In reality 20 MMR isn't a big deal.
MMR in general is whatever. If your winning games your rank will go up eventually.
