When doing the addf j.H in hyper grav loop, there’s very little delay (or none) between :l: and your :h: .
However, since flight loop is done by dashing forward, you need to add a little delay between the dash input and the H. So yeah, it is a bit slower and they will be falling a bit each rep. It’s the same timing as it is on pad, you just feel like it’s a bit different because stick is still foreign to you.
Also, overall stick usage tips: Your type of grip on the joystick is important.
This is how Daigo grips the joystick Here
As you can (hopefully) see, he hs a sort of “I’m holding a wineglass” grip. His pinky (and sometimes ring finger) is on the opposite side of the joystick’s shaft.
For a while i thought this was the “correct” way to do it, when learning stick. But I was really hitting a wall with motions and I was starting to get really pissed. That’s when I saw a justin wong video, and he has a much more relaxed grip Here.
Notice how he simply lays his hand on top of the joystick. I believe he and other old school american player (valle for example) play like this because of the old Bat-tops found in arcades, but it transitions well into balltop grip.
basically, experiment with different grips and see which one fits you the best. Above all, practice, practice and patience! xD
