Description
The BBL GWL Calculator is a professional-grade tool designed for match officials, umpires, coaches, and high-performance staff working in the Big Bash League.
It provides fast, accurate calculations for rain interruptions, over reductions, playing time adjustments, and second-innings scenarios in accordance with the official BBL Playing Conditions.
The app includes:
• First-innings interruption calculator
• Automatic overs reduction and Appendix-style rounding
• Second-innings interruption & termination logic
• Powerplay and Power Surge windows for all reduced-overs innings
• Bowling restrictions for 5-bowler allocations
• Interval reduction when ≥21 minutes are lost
• Late-start guide based on the 175-minute completion window
• Clear timings for innings end, restart, and cut-off limits
All logic runs entirely offline and is optimised for iPad landscape usage.
This tool is designed to support professional decision-making but does not replace the official BBL Playing Conditions, which take precedence in all circumstances.
