This should decide the winner
If SWK wins against UB with a difference of more than 1, then you are mathematically the winners. However, if the case was to be UB winning, tying or losing to a difference of 1 or less, then UB have a chance of getting to first place OR tying with SWK and forcing them to dispute first place with a tiebreaker match.
On the other hand, UB don't have second place assured and SWK do, they'll have to fight for it to win if anything. As for InC, M and JOKER, any of them could reach second place, however I'm afraid it's impossible for them to reach first.
