Absolute best way to practice short shop F-Airs in training mode?

[Scorpi0n1386]

Anyone here have settings known to them that seem beneficial?

There are two ways to short hop Fair. The first is to jump and attack in front of you at the same time. The game recognizes this as a shortcut so you'll automatically do it. However there's not much to practice. The second way is to a short hop, and then use the Fair. This has benefits over the previous method, mainly to delay it so that you can hit short opponents or to combo. I assume you mean this one.
I don't think that there are any setting that would help you hear. The best thing to do is to just practice short hops. Doing it without the shortcut can be difficult at first because the window is so tight (3 frames). So just head to training mode and try to short hop by pressing and releasing the jump button as fast as possible. Do it until you can short hop consistently. This will be very important in general, not just for aerials. When you got that down, then practice by inputting delayed aerials. Good luck!
