Effect of review and patch development experience in the chromium project's patch review time

We analyze effect of review and patch development experience to patch review process in OSS. We use log data from version control system (git and Subversion) and code review system (Rietveld) for the analysis. As a result, both of review and patch development experience showed strong negative correlation with times of review. Further, we added bug (issue) tracking system log data and analyzed with above data as additional analysis. The analysis showed that the experiences did not show correlation with finding bugs in review process.
