"But the surprise is that almost all sports follow exactly the same law–the Pareto Principle. In other words, regardless of the sport, 20 percent of the players enjoy 80 per cent of the success and prize money.

Exactly how this rule emerges in sports with different rules, governing bodies and tournament structures is something of a puzzle.

However, it means there is certain predictability in the outcome of events in which two players are pitted against each other. To test the nature of this predictability, Deng and co have found a model that exactly reproduces the statistics of the real sport.

They make a few assumptions about the players involved, the most interesting being that the probability of one player beating another depends only on their difference in ranking. So the number 1 ranked player is just as likely to beat the number 10 player as the number 75 is of beating the number 85. In fact, the same probability applies to any two players separated by ten places in the rankings. "
