RANKING RULES AFTER 1984


The 1984 reform called for a simpler tournament star system. The ATP decided to give up on the tournament difficulty rating and gave more options for the draw size. At the same time, due to the continuous increase in prize money, stars gained for that were broken down in multiple parts, so tournaments ended up having less stars than before. An important modification referred to the way an average was calculated, the ATP deciding to go for a variable average, in which the divisor was changed the more tournaments a player participated in. As a final modification, the ATP decided to modify the bonus point system, so that players would get rewards for beating players inside of the Top 150 and more of them, especially for Top 20.
