I'll put it this way,
"I don't know what you did, but you did something."
Whatever move you did was obviously a move when done. You have smooth, smooth, and more smooth...kind of jumpy hands that quickly place a card on top (how hard can that be????) and then smooth smooth smooth...
It looked good, but I've seen some just as clean and that are easy, even for beginners.
Edit:: Oh, forgot to mention, just say 'inversion plot' instead of 'I'll find your card by...." it's shorter and recognized.
