I would say without a doubt that Skidude and Rick have a different definition of a level 8-9 skier than JASP and myself. Seems like their definition is more like my level 7-8. I deal with a lot of 7-8 skiers and almost always works on skiing deficiencies as Skidude and Rick suggest.
A level 9 skier in my opinion does not have skiing deficiencies. If you can recognize this you can help the level 9 skier much more than nitpicking on small stuff that does not occur with every turn. All level 9 skiers that I have worked with I have personally known ahead of time.
The conversation goes something like this. Pierre I am trying to (fill in the blank) but don't seem to be able to pull it off every time. Will you take a look and tell me what you see. In most cases the level 9 skier has been pushing the envelope and is outside the traditional box so their timing is not in order and they have no intention of putting their timing in order. They want to know how to pull off what they are doing with the tactics they are using and are usually missing a piece.
If you do not listen to the intent or recognize that this is a skier who does not have skiing deficiencies, you will only waste their time by trying to correct what they are doing to a movement pattern they already own. Just because their timing is off does not mean that they are deficient in their skills or need their firing order of motions corrected to a standard they have long since passed. Their intent means everything in the MA process. If you provide the missing piece, they already have the muscle memory to add the missing piece in.
A level 8+ skier is one who has some skiing deficiencies that I am going to zero in on but here again, what they are asking for may be tactical instead of fundamental and their deficiencies may not always be relevant. If that is the case, I am going to work on tactics instead of zero in on the deficiencies.
With a level 7-8 skier I am almost always going to zero in on a skiing deficiency that is inhibiting what they are trying to accomplish.
Even at this level, you still need to work on skills...it is not nitpicking. And again,sure you work on tactics as well, this is especially true in bumps, trees or gates.....but those are tactics I tell them.....remember my original comment was in response to the idea that you need the student to tell you there intent, or else you cannot do effective MA, somthing I disagree with. You seem to simply be arguing that tactics are important, no argument here....my point is that people often do the..."oh I meant to do that" to mask bad skiing...or "instructors" (especially on this board) do the..."you should have carved more there, with less pivot" as an attempt at MA.
Just FWIW, GCT was introduced to the skiing world by the CSIA at about 4 Interski's ago....so ya, I know it. Nothing I wrote contradicts with your last post or your ideas of it....totally agree that the student's needs come first, but again, that wont effect the MA...if you sit back, you sit back....doenst matter if you want to ski groomers or bumps...the only difference it will make is where (ie physically on the mountain) I improve your skills...
