Boundary Percentage
Definition
Boundary percentage is the share of a batter's runs that come from boundaries (fours and sixes), expressed as a percentage of total runs.
Formula
boundary_pct = ((fours * 4) + (sixes * 6)) / runs * 100
A related variant measures boundaries as a share of balls faced
((fours + sixes) / balls_faced * 100); state which variant is used.
Cricket Interpretation
A high boundary percentage marks a batter who scores primarily by clearing or finding the rope rather than rotating strike. It is a style indicator, not a quality indicator — some elite batters are high-boundary, others are high-rotation.
Required Inputs
fours,sixes— boundaries hit in scoperuns— total runs (for the runs-share variant), orballs_faced(for the balls variant)
Applicable Formats & Leagues
T20 (IPL, MLC), where boundary hitting is central.
Sample-Size Floor
≥ 30 balls faced, consistent with batting rate metrics.
Edge Cases
- All-run scoring (no boundaries) yields 0%, which is meaningful, not missing.
- The runs-share and balls-share variants are not interchangeable — label clearly.
Ranking Rule
Rank descending among floor-eligible batters; always state which variant is ranked.
Known Limitations
- A style metric, not a performance verdict.
- Sensitive to the chosen variant.
Example Questions
- "Which batter scores the highest share of runs in boundaries this season?"
- "Is this player a boundary-hitter or a strike-rotator?"
