I shot the 600 benchrest match at Pascagoula only once but they do the pit deal. I think there was a short zero period maybe 2-3 minutes where the target was pulled and bullet hole spotted. When the sight in period ended the target was pulled down and last hole pasted in a VERY short time period and then sent back up for group to be shot. You shoot two groups while at bench before pit duty and then later come back and repeat the procedure for your last two groups. I will call the match director tomorrow and get the details of how they do it and the time limits. I would really like to do this before season ends.
