Given that what she does in that turn may or may not be skiing gold, what can I do with all that information?
Well if i'm the subject of the video we can refer back to the previous posts.
On the other hand, if i'm a student/athlete looking at the video there are a few things that can happen:
1) I understand very little about skiing, this information could be overwhelming as I am not currently able to perform at a level close enough to implement her techniques.
2) I am an intermediate/advanced skier. I look at it in awe, I see perfection and I am driven to achieve that. Problem is I am not skilled enough yet, so I try to ski like her but I am missing a lot of foundational skills. I need to improve those first.
3) I am an expert/pro/racer. I know what excellent skiing is, I can see and appreciate both the good technical aspects of the turn, and the subtle mistakes. This information reenforces my knowledge. On the slope I can get close to, sometimes even match, her skiing. But I'm not there yet. I still need to iron out MY own mistakes.
So what does this do for me? In the end very little. I am the one skiing, not MS, the information useful to me is the one my coach/instructor gives me about MY skiing, not her because that is not what I look like.
Than, what is the purpose of analyzing a WC racer? It is exactly what is shown in this video. Show tactics rather than technique. So what are the mistakes to be avoided, and what strategies could work better in that specific situation.
Telling the viewers how well she skis, and how she does it might be interesting, educational, and a good reference point of what to aspire to. But in the end nothing of that will directly translate to MY personal skiing experience.
Or at least it won't be as efficient as focusing on personal MA.
So, if I was MS, I might need to know "hey, in this turn you did this and that, and it worked really well. look at your knees/hips/shoulder, remember what it feels like? now compare to this other turn". And also "look here you went too deep, tucked too early, stivoted, let's try not to do it in the next run".
But since I'm not her, it doesn't help me to know that. Not unless I have a direct comparison between what I am doing and her.
Watching awesome videos of other skiers is surely inspirational, but IMHO holds little value as training tool for oneself. This is why the first time you see yourself on video is usually going to have a groundbreaking effect, while the hours spent watching TL ripping not so much.
