I got 1 in 270725, 52*51*50*49/4*3*2*1, I think you forgot that there are 4 ways the first card can be an ace, 3 for the second, etc. Still pretty good, unprecedented, in fact, since no one has EVER done that feat in a verifiable way. Out of how ever many billion people there are, with all the seers on parade. If Cathryn can do that in front of a camera, she's a rich woman.
