title: In New Relic RPM, I get reports with an Apdex index listed. What is the subscript meaning?
body: <p>This sounds ridiculous, but New Relic RPM reports an Apdex index in a form like this:</p>
  
  <blockquote>
    <p>0.92(3.5)</p>
  </blockquote>
  
  <p>Where the 3.5 is subscripted.</p>
  
  <p>What does the 3.5 mean? I can't find the definition anywhere, and yet there it is in my reports, staring me in the face.</p>
