Parallelism
In very minor response to John Shedden's post, [ it's immediately below and you really should take a look ] the only thing I have to say that might be worth listening to is that the skis' parallelism would not I think be related to the shape-outcome of the arc; not at any rate if the timing, the rate, and the amplitude of the skis' tilting and other responses were the same as one another.
Does this make any sense? If I'm not careful I might get so far up my bum that I won't be able to get out and ski!
