Ok, lets break this down. I've done some judging in my day so I'll do my best on an analysis of what the judges might be seeing.
Note, Im taking the run from YouTube, start/stopping and analyzing each trick.
1. 270 on - one-foot - regular out
This trick would be easy to fall under the older mentality of one-foots being seen as sloppy. Even if you didn't score it low due to difficulty, you might give it a low score based on the 'style' or 'form' component. You held it together well, but a judge could very easily view the body positioning of a one-foot as bad. Potentially you could also argue that the one-foot isn't that hard and that a 270 on, regular off is a pretty boring trick.
Of course, you'd have to be smoking acid for any of that to be true... but hey who knows.
2. Rightside 450 disaster, regular out
Your spin on was very solid, but it didn't have mind-blowing style. You missed a bunch of the rail and really only tapped the last 5 or so feet. You stomped it, but didn't spin out or anything, it was just regular. There was tech stuff happening here, and likely you lost a few points because a 450 is dope, but relatively stock in today's day and age.
3. Rightside sw 7 tail -
Now, this trick was fucking dope. Excellent style, well executed, unique, different and cool. However - you're going to score a lower degree of difficulty for the 7, high for the style - but you really only cleared the knuckle by a tiny bit. The issue when you're judging is that people who do super technical tricks, go big but have shit style often are hard to score low against high style, lower difficulty and low amplitude. If you're going to win on style, you need to take a page out of Laurent Favre's book and go fucking DEEP. If you do a 7 in a slopestyle, go at least 3/4 of the way down the landing.
4. Sw left 12 mute -
This trick killed you. You had high degree of difficulty, but the last 540 was completely penciled out, and you totally bobbled that landing. It was nowhere near a complete stomp. The mute grab was nice, but your axis was relatively standard. Amplitude was decent, but not spectacular which is what caused you to have to pencil out of the last 540 of rotation.
5. Front Flip Tail off of 'chicken coop'
Creative, interesting, fun and stylish if you're into that type of a trick. You could have been harmed by opinionated judges on style, but also the front flip could be argued to be lower technicality. I'd gander this a stupid argument personally, but you never know. In this case I'd say it was a solid trick and the variety was a nice change and a good performance on this feature.
6. Mute grab regular slide over rainbow
It would be easy to judge that this had style and creativity, but there were athletes doing very smooth blindside changeups and spins off the same feature. I'd give the flawlessly executed grab epic style points, but you needed a bit of pinache here - like taking it to switch or something - just to add that wow that would have made the judges look. Maybe change the slide into a massive press and you'd add that degree of difficulty that would give youa nudge in the judge's mind.
7. Right 7 mute
Super duper sick. Loved it. Great style, great execution. Go bigger, though this one you did get nice and far down the landing. It was rightside which I can appreciate, but judges often totally forget about this. I'd say you got robbed on this trick, but I might suggest to really shut up the haters go fucking bigger. Charlie Ager style.
8. Right 10 (dub?) octo (?) (please note its been a while since I called tricks)
Flawlessly executed. You needed to go bigger though, as the spin looked rushed for some reason. As well the killer here was the bobbled landing. You can clearly see in the video that you landed a bit backseat and a touch off balance, as the tails of your skis wedge out just for a fraction of a second to regain balance. You were totally in control, and you stomped it - but that wedge is something that sticks out like crazy to judges.
So in closing, I'd still say you got robbed - but I'd reduce it from grand theft to a misdemeanour. My entire ski career I battled with judging, and my entire judging career I battled with other judges.... all fighting about where style and creativity fit in.
I think the whole judging system is broken, and completely favors Degree of Difficulty over anything else. It goes back to our aerials roots where we just can't get over making that one extra rotation win.
However, any old school freestyler will tell you without a doubt - amplitude fucking matters. If you want to absolutely silence the judges, win the crowd and even if you got robbed still win the day.... you must take every trick to the gucci plateau. Your knees will be able to take it there, and you will have bitches flocking to your shit.
So young padawan - take your Gangier curse and break it with the lessons we learn from Big Air Dave.
Chin up though seriously man, that was a dope run. I hope you don't think I'm attacking you, I was just trying to give as real of an assessment as I could from what I know of how comps look from the judging booth.
Hang in there... style must live on no matter what.
