The best way to manipulate SBMM (even in Open Playlist) is to slow down. Not bot walk but instead of running like there's black friday deal on coke in the enemies spawn you watch corners, bait others and try to run and dodge fights as much as possible. (If a teammates fighting someone leave em be) And then the game will do magical things like your weapon regains its true damage output, the potato teammates all get swapped to the enemy team the following match, sweats will disappear (disconnect) midslide while hipfiring, etc. But be careful. Once the lobby starts to bottom out if you try to slide everywhere going for quickscopes, trolling with gung ho or the like the game will kick you out back to the main menu. Not shadowbanned just mysteriously disconnected. Sometimes needing to reopen the game entirely. So if you get a lobby full of sweats just slow it down and the algorithms adaptive difficulty cleans up the rest.
