This technique, typically referred to by its initials, provides a mathematical methodology to recalculate goal scores in cricket matches interrupted by climate, reminiscent of rain delays. It considers elements like assets remaining with every group, together with wickets in hand and overs obtainable, to find out a good and aggressive revised goal. As an illustration, if Crew A scores 200 runs in 50 overs and Crew B’s innings is lowered to 40 overs resulting from rain, the system would not merely prorate the goal.
