Well, simply put: IT IS WHAT IT IS!
SCSoccer.com will continue to record "W/L" for overtime matches decided by penalty kicks and "T" for matches tied at the end of regulation that go straight to PKs. That is the way our state (not North Carolina or others) "powers" (ADs) see fit. Feel free to come up with your own record system.
FWIW, when the rankings are considered, matches that are decided by PKs, regardless of OT or not, are considered draws anyway.
