Well...that isn't completely true with all of skiing, racing isn't subjective, and both moguls and aerials are partially subjective, they both have a system where a certain trick is worth a possible amount of points. Like in a range so a 1080 in bumps is worth between 5-7 points (don't know what the points are that was just an example...) I think freeskiing would be good like this just a wider range per trick so that there is alot of room for style.
