This result indicates a potential discrepancy between patch writers and reviewers in their patch evaluation standard. For instance, patch writers may focus on whether the submitted patch works, while reviewers also concern about how well the patch works. Therefore, reviewers consider “suboptimal solution” much more decisive for rejecting a patch. As another example, patch writers might pay more attention to the source code than the documentation. However, reviewers turn out to have quite a low tolerance to documentation that is inconsistent with the changed code. As shown in Table V and Figure 6, patch reviewers assign significantly higher decisive scores to “inconsistent or misleading documentation” than patch writers.
