The Tamil Nadu Premier League (TNPL) is using the Jayadevan system also known as the VJD method. In the 4th match of the TNPL between Dindigul Dragons and Madurai Super Giants, the method was used after it was hampered by rain. The 18 overs a side game was determined by the VJD method and not the traditional and more popularly used Duckworth-Lewis rule. DD won the match by 14 runs as per the VJD method.

It was formulated by V Jayadevan a civil engineer from Kerala and hence is named after him. This isn’t the first time that the method has been used, in the past, it was used  in the Indian Premier League. The VJD method was considered as a replacement for D/L rule by the ICC and for implementation in the IPL.

After considering the options the ICC had in 2012 rejected Jayadevan’s proposed system and stated, “The committee unanimously agreed that there was no evidence of any significant flaws in the D/L method nor did the committee believe that any improvements could be offered by the VJD method.”

The VJD is at a few aspects a correct method of calculation but the ICC decided to continue with the D/L method which was later upgraded as the Duckworth-Lewis stern method. One of the biggest differences is that the Jayadevan method keeps an account that starts with the previous games whereas the D/L method doesn’t consider the batsmen who are there on the strike and not even the form that the team has  been in. These drawbacks definitely call for a change and VJD could well be tried.

While the DL method calculates the score at an increasing scoring rate as the innings progress which isn’t something that can be taken for granted as the situation of the game changes with overs. VJD system, on the other hand, is projected as a scientific alternative which divides the innings into different phases. It considers the field restrictions into effect in the first few overs, the fall in the middle overs and peak in the death overs.
