Real data from 300k+ pull requests across 8k+ contributors. See how PR size, team size, and using Greptile affects your merge velocity.

[PR SIZE ANALYSIS]

Size Matters

How PR size, lines changed, and team size affect merge times

PR Size vs Merge Time

Metric:

Lines Changed vs Merge Time
Calculation: Median merge time by lines changed bucket.

What it shows: PRs over 500 lines have high risk of getting stuck. Files changed is often the strongest predictor of review time, not just lines of code.

Commits per PR vs Merge Time
Calculation: Median hours to merge vs number of commits per PR, with PR count distribution.

What it shows: Granularity directly impacts speed. Single-commit PRs average 17.7 hours, while 25+ commit PRs take 155 hours. Aim for 1-5 commits per PR.

Files Changed vs Merge Time
Calculation: Median hours to merge vs number of files changed, with median lines changed per file. Dual-axis chart shows both time and complexity metrics.

What it shows: Files changed is often the strongest predictor of review time, more so than total lines. Each additional file adds coordination overhead and review complexity.

Addition vs Deletion Impact on Merge Time
Calculation: Median merge time by addition/deletion ratio. Includes pure additions, pure deletions, and all ratios in between.

What it shows: Addition-heavy PRs take longer to review than deletion-heavy PRs. Pure additions are the slowest, while deletion-focused refactoring tends to merge faster.

Break Up Large PRs

Keep PRs under 500 lines to avoid the exponential time penalty

Optimize Commit Granularity

Aim for 1-5 commits per PR for faster reviews

Limit Files Changed

Files changed is the strongest predictor of review time

How Greptile Helps

AI reviews large PRs 5x faster, reducing size penalties

[TEAM COMPLEXITY ANALYSIS]

Team Size Impact on Merge Time

How team size and coordination overhead affect merge velocity

Team Size vs Merge Time

Metric:

Coordination Overhead Analysis
Calculation: Overhead % = ((Team time - Baseline time) / Baseline time) × 100. Baseline is single-author PRs.

What it shows: How much additional time is added due to coordination complexity. Greptile scales teams without proportional slowdown, making large team collaboration more efficient.

Small (1-3 authors)+0% overhead
28.16 hours vs 28.16 hours baseline
Medium (4-10 authors)+27% overhead
35.66 hours vs 28.16 hours baseline
Large (11-25 authors)+32% overhead
37.10 hours vs 28.16 hours baseline
Very Large (25+ authors)+102% overhead
56.92 hours vs 28.16 hours baseline

Limit Team Size

Keep PR authors under 10 to minimize coordination overhead

Streamline Reviews

Use clear review guidelines to reduce back-and-forth

Set Time Limits

Establish review time expectations for faster feedback

How Greptile Helps

Reduces coordination overhead from 98% to 55% for large teams

[CONTRIBUTOR ANALYSIS]

Where Do You Stand?

See how your contribution patterns compare to the community

PR Distribution by Complexity
Calculation: PRs categorized by complexity (lines + files + commits), showing percentage distribution and average metrics per complexity level.

What it shows: Most PRs are simple (≤100 lines, ≤5 files). Complex PRs are rare but take exponentially longer. Benchmark your team against these industry patterns.

Simple29.42% of PRs
Avg: 17.33 lines, 1.44 files, 14.29 hours to merge
Moderate38.02% of PRs
Avg: 102.80 lines, 3.65 files, 26.27 hours to merge
Complex32.56% of PRs
Avg: 3440.11 lines, 26.66 files, 68.05 hours to merge

What makes you a heavy contributor?
Calculation: Based on PR count percentiles from 8756+ contributors. Shows where you stand in the distribution of code contributions.

What it shows: Your contribution tier based on PR frequency. Higher tiers indicate more significant code impact and influence on the codebase.
