- Lines of code (LOC) under review should be less than 200, not exceeding 400, as anything larger overwhelms reviewers and they stop uncovering defects
- Inspection rates of less than 300 LOC/hour result in the best defect detection, and rates under 500 are still good, but expect to miss a significant percentage of defects if LOC are reviewed faster than that
- Authors who prepare the review with annotations and explanations have far fewer defects than those that do not. The cause, presumably, is due to authors being forced to self-review their code.
- The total review time should be less than 60 minutes, not to exceed 90. Defect detection rates plummet after 90 minutes of reviewing.
- Expect defect rates at around 15 per hour. This rate can only be higher with less than 175 LOC under review.
