title: What does Total unique rate in Lizard code duplication?
body: <p>I am using lizard to get code duplication in my project, I have used <a href="https://github.com/terryyin/lizard" rel="nofollow noreferrer">Lizard</a>(open source tool)</p>
  <p>After running the command to get the code duplication command, it shows</p>
  <blockquote>
  <p>Total duplicate rate: 7.95% Total unique rate: 99.52%</p>
  </blockquote>
  <p>I am unable to understand, how the rate is being generated.</p>
