Priscilla's own experiences as an athlete, from what I recall, were so unique in many ways. If I recall correctly, she was the youngest to ever pass her senior tests (figures, free) and in being so exceptionally young (12?) had an atypical rise through the sport. Given how precocious she was, she probably did not achieve all of the competitive success that might have been envisioned for her originally. I recall she did make the 1981 World team, with Elaine Zayak, as Lise Marie Allen surprisingly crumbled at Nationals when it was finally her "turn."
As a coach, she does seem to have uniquely close relationships with her skaters. Ones which almost seem to blur the lines between athlete and friend, almost into the big sister type zone. In some instances, I can see how this can be very welcoming for a skater maybe transitioning from life "at home" with traditional parents, to one at a training center like the one in Delaware. That said, when it becomes time for a firmer hand and the discipline of a task master, this dynamic seems to have its vulnerabilities.
One thing that I always find remarkable actually, is when skaters spend almost the entirety of their careers with a single coach. That is rare and wonderful when it can evolve in parallel with the needs of the skater through each step. An exceptional example of this in my mind was Brian Boitano and Linda Leaver. With Priscilla Hill, I suspect she has a profoundly positive impact on skaters when they work with her, but the profile that she is most comfortable with and the dyanmic that comes naturally to her, don't seem to be ones which suit a majority of skaters, for an extended enough period of time for them to stay.
For Ashley, I love the no-nonsense dynamic that she seems to have with "Mr Nicks" Priscilla had her own influences which Ashley takes with her, as each of her athletes have.
