According to Andy Herrington, who was a member of the three top producing teams (Craig Proctor Team, Dan Plowman Team and Tom & Diane Mitchell Team), you should look at it in the following way. Most of your competitors are going to give up after the lead is rude for the first time. If you want to do better than your competitors, give it another shot.
Everyone is going to give up after the second time, so if you really want to be the best, you need to try one more time.
