They look at head to head matches before looking at round differential. If looking at head to head matches doesn't solve the problem they look at average. For example if navi wins this one and big wins the match tomorrow. They will have the same amount of wins and their head to head matches will be like this.

M3C > NAVI
BIG > M3C
NAVI > BIG

It won't make any sense to qualify a team looking at head to head matches at this situation, so they will look at round differential if something like this happens. If you look at group A you will see that OG LDN UTD is 4th and G2 is 5th. Even tho G2's round differential is higher OG LDN UTD won against G2 and thats why they are above G2 in the leaderboard. (As far as I know.)

As far as I know M3C will qualify even if NAVI wins this match.(M3C won against NAVI in group matches) I'm not sure tho. BIG is the only team that can eliminate M3C right now. (They won against M3C) They are only one win away from qualifying. BIG will have a match with BBL tomorrow.
