I would say the majority of a segment shows the true ability of the skier, not just their dedication to trying something many times. Yes, there are select times when a feature can be sessioned, but you don't have anywhere to practice the exact features you film on. No one gets to ski the same insane line or rail or backcountry jump everyday. They have to have the skills to ski it when they get the opportunity. Comps definitely show your consistency on standard course features, but they don't offer as much creativity or variability as filming does. Filming shows more of the skier's full potential in my opinion.
