The VJD method, also known as the V Jayadevan system, is a proposed method for calculating target scores in interrupted one-day and Twenty20 cricket matches. It is an alternative to the DLS (Duckworth-Lewis and Stern) method. The method was devised by V. Jayadevan, an Indian engineer from Kerala. The VJD method is essentially built around two curves: the "normal" run getting pattern and the "target curve". The normal curve takes into account both the percentage of overs played and the percentage of wickets lost. The normal score curve is obtained by fitting a suitable regression equation for the cumulative overs % and the corresponding cumulative runs scored % . The target score is then calculated by looking at the percentage of runs scored in each of the seven scoring phases, arranges them in descending order of run. The VJD method divides the innings into phases and assumes a high scoring rate in the first few overs, considering fielding restrictions, assumes a drop in the rate in the middle overs, and assumes another rise in the slog overs. The VJD method calculation revolves around two mathematical curves, the normal score curve and the target score curve. The normal score curve is obtained by taking into consideration the scoring pattern of a team with respect to the percentage of runs and overs bowled at different phases of the innings. The target curve is then obtained by looking at the percentage of runs scored in each phase of the innings. The resulting target is then calculated by performing a complex regression analysis. The VJD method is used in certain domestic leagues and tournaments where it has been adopted as an alternative to the DLS method. However, it is not the official rain rule for international matches.
