I could be wrong but I think it's going like this:
If I win the tournament, IR wins the prediction bracket
if bleh or unrealshots wins the tournament, RJ wins the prediction bracket
RJ currently has a 1 point lead, with both RJ and IR predicting bleh makes it to finals. Since their prediction is identical, if unrealshots wins RJ will still maintain a 1 point lead. So it will come down to the finals, where RJ has picked bleh and IR has picked me. If bleh wins the tournament, RJ will win; if unrealshots wins the tournament both sides will be incorrect, and RJ will win by maintaining his 1 point lead. If I win the tournament, IR will surpass RJ in the final match and win the prediction bracket.
While it's possible for me to beat RJ in the prediction bracket, I have identical predictions to IR going forward; so there's no way I can beat him as he's ahead of me by 1. RJ vs IR prediction bracket finals
