I had the same experience in practice mode, but it doesn't make sense to me that the recovery could be completely random. if that is true, it makes the move essentially useless, at least on midair opponents-- who's going to risk falling over after an already-difficult move when you could simply get much easier damage many other ways? and I have a hard time believing they'd bother to put in a move that would be basically useless, because, basically: why bother?
I think it's possible that practice mode has some flaw which makes it seem random when it's not. I seem to remember seeing the same thing happen with other, decidedly non-random moves in the past. In any case, the one thing we would need to prove that it isn't random is someone who can nail it consistently, or at least more consistently than anyone else. So if anyone can get the recovery almost every time they get every just input flash-- speak up!
