International (ODI) cricket has transformed over the years however the rain rule method of setting targets has remained constant for over a decade‚ the Duckworth/Lewis (D/L) method‚ arguably the most statistically influential phenomenon in cricket. While the accuracy of the D/L method has been well analysed‚ the comparison of it to its best alternative has not been given as much attention. The Jayadevan (VJD) method‚ an alternative which has been over looked for the past 10 years by the International
