I believe T11 auction can be explained as follows:
1. If there is no bidder, the auction will end in initial round.
2. If there is only 1 bidder in any round, auction will end and the only bidder will win.
3. If there are more than 1 bidder in any round, a new round will start.
4. If there is no new bidder in any knock out round, auction will end and the leader of previous round win.
You, as leader of round 6, will win after round 7 completed with no bidder (scenario 4).
