I might be confused. I know Athletics is for jump distance, but I thought Acrobatics was for avoiding landing prone.
RAW,
Acrobatics has nothing to do with jumping, or rather with landing after jump. This is purely in the domain of Athletics.
+1 to the whole idea. Personally, I would like to see it this way:
- White - safe landing is guaranteed
- Yellow - success in Athletics is neccessary to stay on foot
- Red - guaranteed prone on landing
