I feel the same, but only on the slide, the A-A was the most fine tuned. As I play it, I'll tend to be more likely slide if I try to move fast. Which is nice enough cause, it's also the use of certain move in SF. The sprite isn't fitting well enough though, and would need a slash effect to make the trick. The down bound of the hitbox isn't big enough too. this attack deserves more fine-tuning.
Like in the process of creation of Street Fighter, fine-tuning animation and properties is a big part of the job, it's also why there is so much balance in modern fighting game. There's some videos of SFV hitbox on Youtube, you'd notice they are really weird :P.
EDIT: In the last 3 days I've been craving the sensation of making and fine tuning animations like that, I think Li will do some other things =).
