Ever since about 3 years ago, judges in major competitions have finally started paying attention to the difficulty of rail tricks, and i think thats why Russ's run wasn't scored well. His rail tricks weren't really that technical compared to the those who were on the podium. I'm not saying they weren't difficult or impressive on an everyday standard, but i agree with the judges(Inb4 Geopper did the same 360 sw up... but Geopper hit the rail not the box).
This is just speculation, but i also think it has to do with his grabs. Judges have been paying much more attention to style (hence Taylor seatons and Duncan adams pipe runs) and, even though Russ' double grabs are difficult, they don't look good. There are plenty of grabs and tricks in the ski industry that are difficult, but we dont do them because they aren't stylish.
Those are my 2 cents
