SF:3S, parrying jump-ins then doing super art?

Hey guys,

Having watched some replays of Q I saw a guy who often wins by using SA2 out of a parry against jumpers. I am having a really hard time replicating this in training mode, and it’s not helping that there’s no input display option- are there any tips towards how fast this is meant to be performed, is it possible to be entering it too fast so that the parry is considered active still? I can SA2 consistently if it’s not immediately after a parry, but I can’t count out the possibility that nerves of the new set-up is making me miss some inputs.
