Body: <p>It seems that the A/B testing is looking at the total number of open. in one case, we were surprised to experience a big difference between two versions, but it turned out that one of the recipient opened the email dozen of time (most likely it was forwarded to a mailing list)</p>
  
  <p>Is there a way to display and compare what really matters (the number of different contacts that opened, not the number of time they opened it)?</p>
