According to the above, I think it should be 1 goodbye (counted as the winning round), 2-34-56-78-910-112-13, if The negative team is 3-4 6-911-12 (whoever loses will be eliminated). This round of 3, 6, 1 1 wins, 4, 9, 12 is out.
The following1-2; 3-4; 5-6; 7-8; The winner (if) 1, 4, 5, 8, 1 1 bye, and the negative team 2-3; 6-7; Win 2, 6, lose 3, 7, and then 2-6. Win 2,6,2-1 1 (Win 2,11), further down:1-4,5. (The winner is 1, 5) The loser is 4-8, and the winner on the 4th is eliminated 8), and then it is 2-4 (2 wins and 4 elimination); Finally, 1-5 (the winner's champion), the loser, competed with the remaining No.2 for the second place (the two runners who lost only one game). I think so. I didn't look closely either.
