From what I understand, there is National Federation criteria list that is being used to determine the winner if it would be the 6th match for BOTH wrestlers. If one wrestler still can wrestle another match, then she is declared the winner.

If both have already wrestled 5 matches, then (in order)....
1) if they have already wrestled in this tournament, then that wrestler is declared the winner
2) a common opponent with win/loss difference
3) if one was penalized for unsportsmanlike
4) fewest penalty points in this tournament
5) most falls
6) most tech falls
7) most points scored throughout the tournament
8) if none of these criteria sort it out, then both are named the same place (I assume that means both are named 3rd or 5th place) and the team points are divided equally between the two wrestlers
