I, of course, mean undetectable at the time of grading. As for future detectability, that's the beauty of SGC's (and now Mastro's) money backed guarantee. If you show them an SGC 60 with a wrinkle that should've been a 40, they will comp you the difference. So, you are protected against that initially undetectable wrinkle.
