I did this for Pearl Jam tickets at Wrigley just last week. Entered both myself and my wife in the Verified Fan presale. I was selected, but she was not.
About 15 minutes before I was able to buy tickets, I got my presale code. When tickets went on sale, you get placed in a waiting room where fans are then randomly selected to move on to purchase tickets. Once you are at that point, if there are still tickets available, you are good to go.
It's a bit nerve wracking sitting there waiting, but I find it a lot less stressful than having to hit refresh every 2 seconds hoping to get in at the right time. At least everyone is in the same boat. I ended up getting two tickets for a very in demand show, so I was quite pleased.
