Mathematical Suggestions to the D/L Rain Method

Abstract

This paper presents mathematical suggestions to the most used rain rule, the Duckworth Lewis method in cricket, used for resetting the match score. IPL Sunrisers team's coach Tom Moody, and innumerable cricketers, statisticians are feeling the need for a correction in the method. Nobody has yet come out with a single solution, common to T20 and ODI, feeling that a "single" solution is not possible. But this paper easily traces a natural mechanism common to T20 and ODI, namely an "integer partition" in the form of "90n 30". Further, it reviews and analyzes the various sections of the D/L method employed in cricket, in the light of modular mathematics, congruence and presents great many surprising things and practical solutions for the ICC to consider.
