It doesn't work (Tekken 7)

Tell me what I'm doing wrong. There's this kind of a sycakka in the game "Calm down you will succeed"

on some forum I read that to get it enough to take Gigas to throw the enemy up to strike two or three blows with a ruga and until he has not touched the floor to cut Rage Art, so there are 10 or 11 strokes, well, and even that it can be done in training mode, in fact, I did, but the achivka did not open. Not only that there was not even a single attempt to defend even though I did it in training and in the arcade and once it turned out in the battles for the treasure, tell me what I do wrong
