Along the lines of Steve's comment... take a straighter line and work more variety of the bump terrain vs just working the rut. The next level up from nice skiing is "wow" skiing. When you do work sideways across the line, use your edges more so that your lateral speed is faster and you can work your skis cross under more. At 10-12 seconds, that turn is kind of banked and you skid out. If you had set up the end of the previous turn with more finish/edge angle/acceleration, you could have let the skis get ahead of you and work for you instead of "having to fold at the waist, then pop up to get your weight inside the next turn". When you let the rut force your hand, you'll often get caught like that.
The turn sequence at 19-20 seconds is getting closer to what I'm talking about.... BUT ... if you can freeze the last turn at 21 seconds just before the feet and the skis go out of the picture (crap -it's time for another Rusty still ...)
, this highlights an example of an opportunity for wow. The skis are on edge above the fall line (really nice) and they are on a fairly high edge angle for this position in the turn (again nice) and the hips are inside the skis (quite nice). Now imagine what this would be like if the knees and the ankles were "driving" the skis onto even higher edge angles. Notice the very slight divergence of the outside ski and the very slight "lazy" left hand position? A focus on "driving" the skis more would get that left side more actively involved in the turn and clean up that tiny divergence.
Skiing with more pizazz means making greater range of movements with your body parts and managing more energy transfer between you, the skis and the snow. It does not necessarily mean going faster, but sometimes trying to crank the speed up can force you to deal with more energy.
Would this bump run pass a level 3 exam? Keep in mind that bump video looks a lot easier than when you're on the other side of the lens. I know some examiners who would tell you nice but not enough if you were training, but would pass this for an exam. IM(NS)HO, this is borderline for passing. However, I am only a level 2 and my training has been in the East with firmer snow conditions and I suspect different performance expectations. These opinions are only worth what you paid to view them. Nolo - are you out there and willing to chime in?
Reviewing this post, I see that once again I've been way too picky. The funny thing about skiing with examiners and demo team people when they self assess their own skiing is that they are extremely picky. I think you have to be picky to get performance improvements at this level of skiing.
