I ran some tests.

It is HIGHLY LIKELY that bKs, T3 and Emp (in this particular order) gain 1st, 2nd and 3rd place.

It kind of comes down to aC and str8 fighting for the 4th place.

Str8 has good chances if they beat aC in the final match 3-0.

aC then has to win AoG and OwZ 3-0 to be sure going to the finals.

If aC wins a 3-0 and a 2-1, Str8 and aC are at draw and special rules have to be applied.

If Str8 wins aC 2-1, aC has to win a 2-1 and lose a 2-1 so that Str8 and aC are at draw. It goes without saying that any score higher will get aC the 4th place, any score lower gets str8 the 4th place.

If Str8 loses aC 1-2, draw will come up if aC loses 2-1 and 3-0.

If Str8 loses aC 0-3, aC will get 4th place no matter what.
