Arm wrestling tournament rounds
University · ●●●●○ 100 pts
In an arm wrestling tournament, 510 athletes participate. A win gives 1 point and a loss gives 0 points. If the winner initially had fewer points than the opponent, the winner additionally receives one point from the loser. In each round, participants whose scores differ by at most 1 point compete. The tournament ends as soon as a sole leader is determined. What is the minimum number of rounds that need to be played?
