title: SonarQube: Qualify Cognitive Complexity
body: <p>I understand what cognitive complexity is and how it will be calculated, but i don't now how to determine what is a good value for that measure, so how complex my code schouldn't be. I need an objective way to estimate it without to compare project against each other. A kind of formula like "complexity/lines code" or something like that. 
  Or if i define a quality gate for a big project how can i calculate the values for it.</p>
