title: Can I use a JMeter Duration Assertion with a variable?
body: <p>I'm trying to assert the response time of several pages but introducing a threshold, let's say:</p>
  
  <ul>
  <li><a href="http://xxxx/login" rel="nofollow noreferrer">http://xxxx/login</a> typical takes: 500ms</li>
  <li><a href="http://xxxx/user" rel="nofollow noreferrer">http://xxxx/user</a> typical takes: 1000ms</li>
  <li>...</li>
  </ul>
  
  <p>So I want to write assertions checking the expected value + threshold, i.e. something like:</p>
  
  <ul>
  <li><a href="http://xxxx/login" rel="nofollow noreferrer">http://xxxx/login</a>: Assert &lt; 500 * (1 + ${threshold})</li>
  <li><a href="http://xxxx/user" rel="nofollow noreferrer">http://xxxx/user</a>: Assert &lt; 1000 * (1 + ${threshold})</li>
  <li>...</li>
  </ul>
  
  <p>For sure I can make the calculation and set the value, but would be nice if I can use a variable.</p>
  
  <p>Would this be possible ?</p>
