here's a good mmc config for ranked (recommended for sumo but can be used for other modes)
14-19 CPS (Extra randomization, inventory fill and maybe break blocks for bedfight)
Any speed below 10, 80 FOV, and 4.6 distance
3.00-3.08 (MAKE SURE TO ONLY USE FOR DIRE SITUATIONS!!!)
Bind Blink + 0,0,100 velocity together and use default blink settings to never lose in sumo. This is what most leaderboard players do and it's hard to get caught if you don't do it before the countdown (Sumo) and disable spectators.
