whether you are PSIA, PMTS, american, aussie, koreans, austrian, park rat, racer, big mountain free skier. IT DOES NOT MATTER. Physics never changes.
you are either making a round turn or you are not
you are either seperated at your femur/pelvis joint or you are not
you are either balance on your outside ski or you are not
you are either able to build pressure into the fall line(or apex) or you are not.
you are either able have your COMCenter of mass, you body) beat your BOS(base of support, or stance skis, or outside ski) to the fallline or you are not
