==Other uses== There are uses of the D/L method other than finding the current official final target score for the team batting second in a match that has already been reduced by the weather. ===Ball-by-ball par score=== [[File:Lords scoreboard.jpg|thumb|300px|Scoreboard showing ball-by-ball D/L Par Score.]] [[File:2015 CWC I v UAE 02-28 Scoreboard (02).JPG|thumb|Many stadium scoreboards do not carry information about par scores during games]] During the second team's innings, the number of runs a chasing side would expect to have scored on average with this number of overs used and wickets lost, if they were going to successfully match the first team's score, called the D/L par score, may be shown on a computer printout, the scoreboard and/or TV alongside the actual score, and updated after every ball. This can happen in matches which look like they're about to be shortened by the weather, and so D/L is about to be brought into play, or even in matches completely unaffected by the weather. This is: *To help spectators and players understand whether the chasing side are doing better or worse than they would need to do on average to reach the target score *The score the batting team's score would be compared to determine which side had won, if the match had to be abandoned right then. It is the par score which is displayed, i.e. the score to tie. The target, to win, score is one run more than this. South Africa exited the 2003 World Cup after a tie [[Duckworth–Lewis method#Reduced target: Team 1's innings completed; Team 2's innings cut short (resources lost at end of innings)|with Sri Lanka]] by mistakenly believing the par score on the printout was the target score<ref>{{cite news|url=http://news.bbc.co.uk/sport3/cwc2003/hi/newsid_2810000/newsid_2816800/2816883.stm |title=South Africa left to lick wounds|work=BBC Sport|date=3 March 2003|author=Thrasy Petropoulos}}</ref><ref>{{cite news|url=https://www.theguardian.com/sport/2011/apr/17/duckworth-lewis|title=Being Duckworth-Lewis: cricket's weather-break mathematicians|work=The Guardian|publisher=Guardian News and Media|date=17 April 2011|author=Barney Ronay}}</ref> ===Net run rate calculation=== It has been suggested that when a side batting second successfully completes the run chase, the D/L method could be used to predict how many runs they would have scored with a full innings (i.e. 50 overs in a One Day International), and use this prediction in the [[net run rate]] calculation.<ref>{{cite web|url=http://www.sporttaco.com/rec.sport.cricket/Net_Run_Rate_alternative_3979.html|title=Net Run Rate alternative|work=SportTaco.com|author=Peter Foster|date=15 April 2007}}</ref> This suggestion is in response to the criticisms of NRR that it does not take into account wickets lost, and that it unfairly penalises teams which bat second and win, as those innings are shorter and therefore have less weight in the NRR calculation than other innings which go the full distance.
