What is the VJD method in cricket: The VJD method, short for the V. Jayadevan method, is a system used to calculate revised targets in rain-affected limited-overs cricket matches, including ODIs and T20s. Developed by Indian civil engineer V. Jayadevan from Kerala, the method was designed as an alternative to the ICC’s widely used Duckworth-Lewis-Stern (DLS) system.
The VJD method is officially adopted in several Indian domestic competitions under the Board of Control for Cricket in India (BCCI), though it is not used in international cricket governed by the International Cricket Council.
Principles of the VJD method
Unlike DLS, which relies on abstract “resources,” the VJD method models an innings based on realistic scoring phases seen in modern limited-overs cricket. It divides an innings into three clear segments:
- Powerplay overs – high scoring due to fielding restrictions
- Middle overs – steadier run accumulation
- Death overs – accelerated scoring and slog overs
The system uses two mathematical curves:
- A curve representing normal scoring progression
- A second curve accounting for acceleration after interruptions
By factoring in overs remaining, wickets lost and the first-innings total, the VJD method recalculates targets using interpolation tables that aim to preserve fairness and match context rather than relying on generic averages.
Example: how VJD revises a target
Consider a 50-over match where:
- Team 1 scores 280 runs in 50 overs
- Rain reduces Team 2’s chase to 40 overs
Under the VJD method, 40 overs equate to roughly 87.6% of total scoring resources based on its phase-weighted tables.
The revised target becomes:
280 × 87.6% ≈ 246 runs
Supporters argue this approach better reflects the value of lost death overs compared to DLS, which applies more standardized resource percentages.
Usage, approval and debate
The VJD method was introduced in 2007 and later approved by the BCCI for use in Indian domestic cricket. It is applied in domestic ODIs, T20s and leagues such as the Tamil Nadu Premier League (TNPL). Dedicated apps and software also allow scorers to calculate revised targets in real time.
However, the ICC has chosen not to adopt VJD for international matches, continuing to use DLS instead. While critics cite consistency and global standardization as reasons, proponents argue that VJD is better suited to modern, high-scoring cricket, especially in T20-heavy eras.
The VJD method remains a significant and uniquely Indian innovation in cricket mathematics. While it operates largely outside the international spotlight, its emphasis on innings phases and realistic scoring patterns keeps it central to ongoing debates about how best to handle rain interruptions in contemporary cricket.
