title: GitHub makes my green squares less green the more I commit. Why?
body: <p>Everyone knows that the more you commit to github in a single day, the darker green your square is on your profile. </p>
  
  <p>But the more you commit it seems that GitHub retroactively goes back and lightens your dark green squares. </p>
  
  <p>Does anyone know the formula for how GitHub does this? </p>
  
  <p>Bonus question: One of the most active people on GitHub had over 2000 commits on a single day. Any guesses on what was going on that day? Scripting? Hacking? Single letter commits? </p>
