Rain-hit international matches are set to become fairer with a revision to the infamous Duckworth/Lewis method. The system has gained plaudits since its introduction worldwide in 1999, despite criticism of its complexity.
But co-inventors Frank Duckworth and Tony Lewis found inconsistencies in high-scoring matches.
"The ICC believes that this change ensures that the system is now more accurate in setting targets," said ICC general manager David Richardson.
With rain threatening in March's World Cup final, India were in apparent trouble at 145-3 after 23 overs, chasing Australia's mammoth 360.
But they could have taken the title simply by scoring 12 runs in the next two overs, had the heavens then opened.
"We have had the answer to this problem available for use for several years," explained Lewis.
"Using the Professional Edition of the D/L method, India would have been 20 runs behind par - a much fairer reflection of the state of the game."
The International Cricket Council (ICC) will introduce the new Professional Edition for Friday's opening one-day international between Pakistan and South Africa.
The new system is more complicated than the original and will be entirely computerised.
But the existing edition, which can be calculated manually, will still be available for domestic competitions and at grounds withouth computers.
