Replying to Blue mtn PA big air comp

So I learned the other day that at a big air comp, difficulty really has nothing to do with the score. I went out an did a cork 7 saftey grab and sketched the landing and ended up getting 3rd. Now the two guys that beat me threw straight airs or 360's. I'm a little confused on what the hell happened yesterday. I understand that these two guys didn't sketch out on their landings, but fuck, a straight 3 beat a cork 7. Any thoughts?
