**Claim.** Patch size degrades multiple dimensions of code review performance at once: comment density per reviewer falls as patches grow, the quality and amount of contribution is affected, and the time required to provide significant contributions increases.

**Type.** empirical  **Support.** evidenced

**Holds when.**

- studies measuring comment density against lines of code

**Source quote.**

> found that comment density by reviewer decreases as patches increased. 18 Accordingly, the quality and amount of contribution is affected by patch size.19 And, patch size increases the time required to provide significant contributions.20
