Whoo, did the Evo Moment #37 parry trial! Lots of fun once you get it down.
The trick (writing down so I don't forget):
Parry 1: the first parry has to be inputted a split second before the super activates. If you're character steps forward more than a pixel, you did it too early and you're probably not going to get the parry.
Parry 2: this is crucial that you don't press forward when the first parry hits. This was my problem. It's too early. You have to wait for parry #1 to happen, then continue parrying. Counting out loud helped me do this (press forward, super activates, count ONE when parry occurs, then continue parrying on two).
For the rest of the timing, just watch Evo Moment #37 until the timing is seared into your brain (7,7,1). Then jump parry the last hit, and do the jumping roundhouse kick very very late.
