You can't try to judge a movies play by "how the original author intended." Here is an example of what I mean:

If you do Z+B on the correct frames, it not only maintains speed, but it continues to grow as well. The jump kick trick is very similar to this as well (but better for shorter distances). They are obviously considered glitches, but the average person that watches it wouldn't even notice that the player did a slide kick instead of a jump dive or something else "intended."
Another example would be a wall kick.
Anytime you do a first frame wall kick, you are starting a chain of HSWK, because all "perfect" wall kicks maintain speed (again, breaking the intended amount).
You guys will have a tough time deciding what to enable/disable on a 70 Star run (which I think is just as arbitrary as this 16 Star movie).
