3 and 4th place Determination

[GamerC]

I was wondering how to determine between 3rd and 4th place in a top cut of 4. There was no match between the two.

Side info:
One battle was 5-0 against a 4-1(A), with the 5-0 winning.
One battle was 4-1(B) against 4-1(C) with 4-1(B) winning.

the 4-1(A) lost his/her battle
the 4-1(C) lost his/her battle

1st place ended up being 4-1(B)
These battles were best 2 of 3.

I'm leaning toward that 4-1(A) got third, but not 100%. If it's like opponent's opponent % or some weird stuff like that I don't know.

It goes by the standings at the end of Swiss.
So, whichever of the two players were ranked higher at the end of swiss, that player would be in 3rd place.
Note that TOM does this automatically, so for any Premiere Event, that must use TOM, you don't need to figure it out yourself.
