I'm not out to bash anyone, just applying critique where I think improvement is needed - in my opinion, they could do so much better on the technical side. The reflective learning and all that, is good. The reason I'm trying to progress along that CSIA path is not in order to bash it, but to understand better and it is true, that as one moves higher, it gets more specific and interesting.
And we know that other countries do better, because we can see their skiers at the Interski... there's a lot of them (Australians, NZ, Swiss, Austrians to mention a few) so the potential is there... so the only question is not whether we do better, we know we don't - but how do we progress from what we have now to better.
Btw, I did not say at any point that you one can pass certain levels without knowing how to ski or teach to standard, just that the technical part is not standardized in detail in any manual that I know of. It is explained and taught to some extent by word of mouth at those training courses, but there will always be differences in how different trainers explain the things that are not written in a manual... so one's mileage will always vary - and your experience seems to confirm exactly what I stated...
Why can't it be that there is a clear manual, we all read and follow?
Laying it out? Here's one model of exactly what to do, my 1-2-4:
1. tip the feet on edge
2. use the upper body to balance as needed on the outside ski
4. counteract the rotation and
3. the skis will turn
The more you do 1,2,4 - the more grip you have, so the faster you can go and/or the tighter you can turn. It wouldn't cover all about bumps for instance, I guess - but realistically perhaps that's why these "generic" frameworks fault out, because they try to be too "generic"? Even though a few skiers jump and some ski bumps, most skiers still ski groomers. Or at least should learn to...
Here's another one, more detailed and more specific, that I just made up:
1. release the previous turn smoothly: untipping the feet while flexing and relaxing
2. continue to tip the feet onto the new edge, while staying relaxed over terrain
3. balance on the outside ski, angulating as needed as grip increases
4. counteract the coming rotation of the skis
5. keep your ankles closed (dorsiflexion), to stay balanced fore/aft
You'd hear JFB talk a lot about relaxation and skiing in suspension versus skiing in compression... I think the one above captures that too, as well as bumps and rough snow etc - although that's more tactics.
Then of course, we have this more complete framework:
1. tipping
2. flexing
3. dorsiflexion
4. counterbalance
5. counteract
6. use of poles and upper body coordination
These all teach one specifically what to do to ski well, from a technical standpoint, i.e. the "what". Then of course you have tactics: the "when", the timing of the "movements" you do...
