The dead rubber match therefore has no effect on the winner and loser of the series, other than the total number of matches won and lost and the statistics of the players.
For example, in a Davis Cup series, each pair of competing countries play five matches (rubbers) where the winner is decided on a best-of-five basis.
International Tennis Federation's last revision of the competition policies on dead rubbers is from 2011.
[1] Since the result of a dead rubber has no impact in determining the winner of a series, dead rubbers are typically played in a less intense atmosphere, often allowing the team that has lost the series to obtain a match win.
This practice makes completing a clean sweep of a series less likely, so in Chinese, dead rubber is often called 'match for dignity' (Chinese: 荣誉之战), mostly for compititors that lost chance to advance.
