===Step 2. Convert the two teams' batting resources into Team 2's target score=== '''Standard Edition''' *If R2 < R1, reduce Team 2's target score in proportion to the reduction in total resources, i.e. '''S × R2/R1'''. *If R2 = R1, no adjustment to Team 2's target score is needed. *If R2 > R1, increase Team 2's target score by the extra runs that could be expected to be scored on average with the extra total resource, i.e. '''S + G50 × (R2 – R1)/100''', where G50 is the average 50-over total. Team 2's target score is not simply increased in proportion to the increase in total resources, i.e. S × R2/R1, as this 'could lead to some unrealistically high targets if Team 1 had achieved an early high rate of scoring [in the [[Powerplay (cricket)|powerplay]] overs] and rain caused a drastic reduction in the overs for the match.'<ref name=FAQ/> Instead, D/L Standard Edition requires average performance for Team 2's additional resource over Team 1. '''G50''' G50 is the average score expected from the team batting first in an uninterrupted 50 overs-per-innings match. This will vary with the level of competition and over time. The annual ICC Playing Handbook<ref name="ICCPH"/> gives the values of G50 to be used each year when the D/L Standard Edition is applied: {| class="wikitable" |- | width="160pt" align="center" | Period | width="180pt" align="center" | Matches involving [[List of International Cricket Council members#Full Members|ICC full member nations]] | width="180pt" align="center" | Matches between teams that play [[first-class cricket]] | width="100pt" align="center" | Under-19 internationals | width="100pt" align="center" | Under-15 internationals | width="180pt" align="center" | Matches between [[List of International Cricket Council members#Associate Members|ICC associate member nations]] | width="100pt" align="center" | [[Women's One Day International cricket|Women's ODIs]] |- | align="center" | 1999 − 31 August 2002<ref>{{cite web|url=http://www.rediff.com/sports/1999/sep/16guest.htm|title= The dummy's guide to Duckworth-Lewis|author=Dr Srinivas Bhogle|date=16 September 1999|work=Rediff on the Net}}</ref> | rowspan="1" colspan="1" style="text-align: center;" |225 | rowspan="2" colspan="5" style="text-align: center;" | ? |- | align="center" | 1 September 2002 − 2006<ref name="DLM2002">{{cite web|url=http://www.espncricinfo.com/ci/content/page/409996.html |title=The Duckworth-Lewis Method (2002)| author1=Frank Duckworth|author2=Tony Lewis|year=2002|work=Cricinfo|publisher=ESPN Sports Media}}</ref> | rowspan="1" colspan="1" style="text-align: center;" |235 |- | align="center" | 2006/07<ref>{{cite web|url=http://www.toxovolia.com/downloads/cricket/ICC%20HB%20E-Book2.pdf|title=ICC Playing Handbook 2006-07|access-date=18 April 2014|archive-url=https://web.archive.org/web/20160303224031/http://www.toxovolia.com/downloads/cricket/ICC%20HB%20E-Book2.pdf|archive-date=3 March 2016|url-status=dead}}</ref> | rowspan="3" colspan="3" style="text-align: center;" |235 | rowspan="3" align="center" | 200 | rowspan="3" align="center" | 190 | rowspan="3" align="center" | 175 |- | align="center" | 2007/08 |- | align="center" | 2008/09<ref name="ICCPH"/> |- | align="center" | 2009/10<ref name="ICCPH"/> | rowspan="5" colspan="2" style="text-align: center;" |245 | rowspan="5" colspan="4" style="text-align: center;" |200 |- | align="center" | 2010/11<ref name="ICCPH"/> |- | align="center" | 2011/12<ref name="ICCPH"/> |- | align="center" | 2012/13<ref name="ICCPH"/> |- | align="center" | 2013/14<ref name="ICCPH"/> |} Duckworth and Lewis wrote:{{blockquote|We accept that the value of G50, perhaps, should be different for each country, or even for each ground, and there is no reason why any cricket authority may not choose the value it believes to be the most appropriate. In fact it would be possible for the two captains to agree a value of G50 before the start of each match, taking account of all relevant factors. However, we do not believe that something that is only invoked if rain interferes with the game should impose itself on every game in this way. In any case, it should be realised that the value of G50 usually has very little effect on the revised target. If 250 were used, for instance, instead of 235, it is unlikely that the target would be more than two or three runs different.<ref name=FAQ/>}} '''Professional Edition''' *If R2 < R1, reduce Team 2's target score in proportion to the reduction in total resources, i.e. '''S × R2/R1'''. *If R2 = R1, no adjustment to Team 2's target score is needed. *If R2 > R1, increase Team 2's target score in proportion to the increase in total resources, i.e. '''S × R2/R1'''. The problem of early high scoring rates potentially producing anomalously high targets has been overcome in the Professional Edition, which is essentially 'a different table of resource percentages for every total score in the Team 1 innings.'<ref name=FAQ/> Therefore, Team 2's target score can be simply increased in proportion to the increase in total resources when R2 > R1,<ref name=FAQ/> and there is no G50.
