Does anyone know if the use of Same Day Confirmed changes the likelihood of a triple beep? I have had a terrible hit rate lately (was ~20/20 originally, but have but 0/10 lately) and am wondering if my SDCs could be affecting the hit rate. My middle name is on my profile and @deltaassist confirmed that everything appears to be setup properly. I've read through the last 12 pages of the thread and have not been able to find an answer.
I missed another flight yesterday by 3 minutes and pre-check definitely would have made the difference...
