Can you (or anyone) explain what “wrestle for true 7th” means? Does it mean the loser of the fifth place match wrestles the guy who lost to the 5th place wrestler in the previous round?
"True" placing matches are only for even-numbered places (2, 4, 6).
For true 6th, the loser of the 5th-place match faces the winner of the 7th-place match. The exception is if they've already faced each other earlier in the tournament. In that case, the winner of that previous match is declared true 6th.
