7-7 WRESTLER'S PREDICTED WIN PERCENTAGE AGAINST 8-6 OPPONENT: 48.7
7--7 WRESTLER'S ACTUAL WIN PERCENTAGE AGAINST 8-6 OPPONENT: 79.6
So the 7-7 wrestler, based on past outcomes, was expected to win just less than half the time. This makes sense; their
records in this tournament indicate that the 8-6 wrestler is slightly better. But in actuality, the wrestler on the bubble
won almost eight out of ten matches against his 8-6 opponent. Wrestlers on the bubble also do astonishingly well
against 9-5 opponents:
7-7 WRESTLER'S PREDICTED WIN PERCENTAGE AGAINST 9-5 OPPONENT: 47.2
7-7 WRESTLER'S ACTUAL WIN PERCENTAGE AGAINST 9-5 OPPONENT: 73.4
