Boris shared the size distribution across those 141 PRs, totaling 45,032 lines changed (additions + deletions):
| Metric | Lines (add+del) | Meaning |
|---|---|---|
| p50 | 118 | Median PR size — half of all PRs were 118 lines or fewer |
| p90 | 498 | 90% of PRs were under 500 lines |
| p99 | 2,978 | Only ~1 PR exceeded ~3K lines |
| min | 2 | Smallest PR — a quick 2-line fix |
| max | 10,459 | Largest single PR — likely a migration or generated code |
- A median of 118 lines means most PRs are focused and reviewable, even at 141 PRs/day
- The distribution is heavily right-skewed — the occasional large PR is inevitable (bulk renames, migrations), but the norm is tight
- Small PRs reduce merge conflict risk, are easier to review, and pair perfectly with squash merging for clean reverts
