I was playing Overwatch a bunch this weekend and was trying to climb in competitive so I played with a couple friends as well. I noticed that there seems to be a big difference between the SR gained when playing solo vs playing with a group.
I was earning upwards of 30-35 SR per win alone, with 1 friend I was getting around 20-25, and with a group of 4-6 people I was only getting upwards of 15 SR per win.
I tried looking up to see if Blizzard had released any sort of formula for how it's determined, but wasn't able to find anything, maybe I missed something.
So in short, is there a formula, or some way that SR is determined the more players you are grouped with?
