YM here is my take. I may not answer each question directly but I hope I am addressing what you are scratchin at
First, I would like to comment on Bob's A B slope graphic. While it is clearly well done and technically correct, I can't understand why we continually focus on resultant forces with no mention of the only force that is defined by circular travel...Centripetal.
Since centripetal force is generated by the skier, creating circular travel with one's skis is driven by intent...what is to come. Not what is.
Centrifugal force is the phantom resultant force created by centripetal force. In reality, it is just our mass trying to return to straight line travel.
If you build your skiing technique based on addressing Centrifugal force not only will you have a high likelyhood of not completing your turn, you will quickly find yourself behind in the action.
IMO all ski turns (circular travel) generate centripetal force. Only our intent, dictated by both free choice, terrain and obstacles will determine how quickly and to what extent we need to create and build centripetal travel through the use of our skill sets. We can rotate in or we can carve start to finish.
For me, centrifugal force is a feedback that confirms my intent. But many lower end skier treat it as a warning just like in a car when you are turning too tightly. The difference is that the friction between the tires and the road is what it is and on skis it just means you are being successful.
So what makes turns different? And how do we decide? Since IMO a turn is about creating centripetal force, the big difference is how we enter the centripetal process and the techniques used to create higher edge angles. Do we need to forego the pure attainment of edge (of which there are a number of techniques) and use rotary because of space and time constraints? Either way,
all turns are created using a combination of the BERP skill set..... and that's why it is not going away
