Analytics Explained
Deep dives into our three exclusive cricket intelligence metrics.
Momentum Map
Over-by-over battle visualization
The Momentum Map answers the question every cricket fan asks: "Which overs defined this match?"Each bar represents a single over. The height shows how many runs were scored. But the real intelligence is in the color:
The overlaid line shows the cumulative run rate, giving context to whether the team accelerated or slowed.
Bowling Pressure Index (BPI)
Composite bowling performance score
Economy rate alone is misleading — a bowler who goes at 8 but takes 3 wickets is far more valuable than one who goes at 6 with no wickets. BPI is a proprietary composite that weighs three dimensions of bowling impact into a single pressure score.
Contextual Batting Index (CBI)
Phase-aware batting performance score
A strike rate of 140 in the death overs under pressure is far more valuable than 140 in the first over of a powerplay with no wickets down. CBI adjusts for both the phase of the game and team context.
A context multiplier further adjusts the score based on match situation — batting with more wickets fallen is harder and is rewarded accordingly.
Frequently Asked Questions
Quick answers to common questions about our analytics engine.
What is a Cricket Momentum Map?
A cricket Momentum Map is an over-by-over visual chart that tracks team control in a match. Height represents runs scored, and colors indicate dominance: green for batting dominance (9+ runs), dark grey for bowling pressure (<5 runs), yellow for contested overs (5–8 runs), and red when a wicket falls.
How does CricRover calculate the Bowling Pressure Index (BPI)?
The Bowling Pressure Index (BPI) is a composite metric combining dot ball percentage, economy rate efficiency, and wicket-taking impact. It evaluates a bowler's overall pressure output on the game rather than just their economy rate.
What is the Contextual Batting Index (CBI) in cricket?
The Contextual Batting Index (CBI) is a phase-aware metric that rates batting performance against situation-specific expectations (such as Powerplay, middle, or death overs) and the number of wickets fallen. A score above 100 indicates outperforming expectations.
Why is BPI better than a bowler's Economy Rate?
BPI is superior because it rewards wicket-taking and dot balls, which are the primary drivers of match momentum, whereas economy rate only measures runs per over and can be misleading.
How does CricRover differ from traditional cricket scorecards?
CricRover uses advanced calculations to provide real-time BPI, CBI, and Momentum Maps that show context, pressure shifts, and match control, going far beyond raw scorecards.
