Expressed differently, it is the total number of runs required of the batting team to win the match, divided by the total number of overs remaining in the match.
[2] Higher required run rates are more difficult to achieve, since batsmen are forced to score more runs within a limited number of deliveries from the bowling side.
[3] The required run rate can also be used in Test cricket, usually in the fourth innings of a match, when the batting side is chasing the opposing team's total with a limited number of possible overs left to play, though use of the term is less common in this form of the game.
[4] In recent times, required run rates have often tended to be particularly high as batting sides have grown increasingly accustomed to chasing high run totals, especially in Twenty20 cricket.
[5] In matches with tiebreakers (such as a Super Over), a chasing team can win the game while scoring slightly below the required run rate, so long as they tie with the other team.
