title: Time to understand a program by LOC
body: <p>Are there any broad, overgeneralized and mostly useless rules about how long it will take to understand a program based on the number of LOC (lines of code)? </p>
  
  <p>(I understand any rules will be broad, overgeneralized and mostly useless. That's fine.)</p>
  
  <p>(The language in question is Delphi, but that shouldn't matter because I'm looking for broad, overgeneralized and mostly useless rules.)</p>
