-Besides this, Codacy also allows you to compare issues across repositories with different sizes by calculating the issue cost **relative to a baseline of 1 point per line of code**, where the cost of each issue depends on its severity: Critical = 10 points, Medium = 5 points, Minor = 1 point. This means that if your repository has 50% issues, the amount and severity of the issues in your repository is half of the baseline.
