This is what I think the “philosophy” of the CoP should be. There is a certain base level of expectation for every skater competing at the senior championship level. Ladies at this level should all be able to present all the triples through the triple Lutz (correct edge), and men should show mastery of all six triple jumps. Besides that, all senior level skaters should be required to show competency in each of the three types of spins, with variations and combinations, as well as a full complement of steps, turns, and unscored moves in the field, including spirals for ladies.
As the IJS puts it, they should show a mastery of "the vocabulary of figure skating."
To fulfill this aim the CoP should be weighted and structured, in so far as possible, in such a way that skaters who cannot attain this minimum content will not be in podium contention.
Now we have to decide the medals. To win the contest, a skater must show more than the minimum. There are various avenues available for this. A man can do a quad, a lady can do a triple Axel or a difficult triple-triple. Alternatively, a skater can try to soar above his fellows in terms of quality – don’t just do a triple flip and a sitspin, do an exceptionally good flip and sitspin (hence GOEs).
Or a skater can try to stand out by putting greater effort into choreography and musical interpretation (hence the PCSs). However, in my opinion, the structure of the CoP should not encourage skaters to substitute these medal-winning extras for basic competency.
This does put a burden on the judges – is this guy’s quad worth more than that guy’s choreography or the other guy’ spins and moves in the field? But that is why we have judges.
