Frequently Asked Questions
How long should a code review take?
Research from SmartBear suggests reviewing no more than 200-400 lines per hour for effective defect detection. Reviews longer than 60 minutes show diminishing returns. Ideal PR size is under 200 lines. For a 200-line PR, expect 30-60 minutes depending on complexity.
What is the optimal PR size?
Studies show PRs under 200 lines have the highest defect detection rate (60-70%). PRs over 400 lines see detection drop to 20-30% as reviewer fatigue sets in. Google recommends PRs under 100 lines. Split large changes into focused, reviewable chunks.
