Great job, MA, on your opening post. Very well thought out and complete.
In racing, focus is placed on efficency of movement, so the technicals found there are very applicable to recreational skiing.
As to inside ski use; I would categorize it as supplimental. The outside ski is still the work horse, carrying the primary load and dictating the course of travel. Generally, the inside ski harbors only a minor portion of the load, though it's sometimes granted a situational leading role, and is always available as a safety valve.
Tipping of the inside ski in semi harmony with the outside ski allows it to cut a similar path to the outside ski, which minimizes needed for line of travel correction. Tipping the inside ski also opens the kenetic gate to optimal functionality of the pelvis and allows for maximum inclination onto high edge angles.
That said, I'll go on to suggest that the primary means of producing concentric arcs of the inside and outside skis are not through micro management of edge angle and pressure (to always ensure a pure and harmoniously carving inside ski), but rather through the tensioning I described above. While micro managing the inside ski carve is possible at low edge angles, it's a more labor intensive option than just general angle simulation with the difference made up via tension. It also becomes nearly impossible to achieve pure inside ski carving at high edge angles because of the severe contortions/inclinations of the inside leg that must occur to make it happen.
If you closely examine WC GS shots you'll typically see outside ski edge angles larger than inside ski edge angles. That evidence makes it obvious that the inside ski is not pure carving, and that some means of compensation is being employed.
