Duckworth and Lewis wrote, "When the side batting first score at or below the average for top level cricket ..., the results of applying the Professional Edition are generally similar to those from the Standard Edition. For higher scoring matches, the results start to diverge and the difference increases the higher the first innings total. In effect there is now a different table of resource percentages for every total score in the Team 1 innings." The Professional Edition has been in use in all international one-day cricket matches since early 2004. This edition also removed the use of the G50 constant when dealing with interruptions in the first innings.
