It has become an accepted part of limited-overs furniture, if not universally liked, but tonight the International Cricket Council will study an alternative to the Duckworth Lewis system.
The D/L method, used to recalculate targets in rain-hit one-day matches for 12 years, was designed by Englishmen Tony Lewis and Frank Duckworth.
They devised their system after cricket's most ludicrous climax to an ODI - in the 1992 World Cup semifinal, in Sydney, when South Africa's target of 252 off 43 overs became 22 in one ball after a short rain break.
Several other systems were tried and found sorely wanting. Duckworth Lewis may not be perfect but is seen as the best alternative.
Now an Indian engineer, Vasanathan Jayadevan, has proposed an alternative. It has already been assessed by the ICC, whose cricket committee, headed by former West Indies skipper Clive Lloyd, will study it at Lord's when their meeting starts tonight (NZT).
