Welcome to the world of ski forum coaching!
From your first post above, and your other posts so far on epic, I get that this is your second year skiing, that you ski in NH, and that you have taken lessons. You are interested in mastering speed, and consider being able to make very, very short radius turns getting down the hill at high speed and skiing blues and blacks at high speed as signs of increasing skill. You clock your speed to document how fast you go. You are not alone; others think this way as well.
You want comments here maybe in order to confirm your quick progress, and also to help you clarify what's good with what you are doing. You also may be hoping for some suggestions about your pole plants that you can improve on.
You may get more than you bargained for, so get ready.
First thing you need to know is that there are a lot of instructors with tons of experience who may post in this thread. Listen to them, even if you don't like what they say. Second thing you need to know is that the way to improve is to lose your focus on speed and work on gaining technical prowess. Going fast down something without having a serious accident does not mean you did it the way an expert does it. You are still at the beginning of your learning curve, and going that fast may put you and others in danger if your stopping and turning skills are not yet well-developed enough to enable you stop on a dime, should something unexpected happen. Certain things about the way you are skiing, and the way you stop at the end of your run indicates that this is the case. Thus Metaphor's harsh post.
Given your aspirations and the intensity of your desire to become an expert skier, you will succeed.... IF you shift your focus. You need to learn to manage your turns with high skill at slow speeds on easy terrain, and only then move those skills to higher speeds and steeper pitches.
Perhaps you can do more turning than this video shows, but did not video those turns because you were happier with this fast way to get down a trail. You might consider posting a video of full turns, and take the comments of the pros very seriously when they give comments. I am curious about your instructor focusing on pole plants. What did you ask for in the lesson, and what was the intended outcome of using pole plants?
