But to improve your carving you need to improve your pivoting. The last part of the video on the steeper sections tell the whole story. Compare your "pivot point" to the White Knight. White Knight is pivoting to start those turns, but he pivots right under his foot, so when the skis touch down, the tip catches and he is immediatley into a great high performance carve. Your pivot point is forward, causing the tails to displace, this is prevents you from getting that same carving performance that you get in the easier sections of the run.
I have written this a 1000 times here...the difference between a good pivot and bad pivot, is a good pivot can be turned into a carve at any time, a bad pivot cant.
Draw a straight line in the snow, straight down the fall line.
Do pivot slips or spiess down the line...make sure your feet stay on the line.
