To me, the annual inflation in PCS is just stupid.Is the entire concept of IJS supposed to eliminate the subjectivity of 6.0?
There's no way to get rid of all subjectivity when a large part of the scoring is, by nature, based on human evaluations of qualitative variables. E.g., if "edge quality" is important (and it is and always will be as long as figure skating remains figure skating -- it's one of the fundamentals of the sport), then humans need to perceive and evaluate it. Judges can be as honest and unbiased as we like, but they're always going to be human beings subject to the limits of human perception. That kind of subjectivity is unavoidable.
But other technical aspects of the performances are less subjective. You either rotated a quad or you didn't. You landed it on one foot or you didn't. You rotated a twizzle four times or you didn't. You achieved a sitspin or camel/spiral position that meets the minimum definition of the position and held it for the minimum length of time, or you didn't.
Those kinds of details can be determined objectively, with the use of video replay where necessary.
So instead of leaving it up to each judge to notice (or not notice) each of those details and rely on their own opinions as to how much each one matters, the IJS assigns a separate set of officials to keep track of the definitions and to determine, with video replay, exactly what each skater executed. Every skater who executes a move that meets the same definition gets the same base mark for that move. That's a level of objectivity that didn't exist under 6.0.
Of course, different skating insiders (and fans) have different opinions about how much various skills should be rewarded or whether they're important enough to reward at all. Thus we have debates over rules for what's required in each program, rules for defining each kind of element including what features add to the levels. People continue to disagree, and as the consensus of opinion shifts on certain points, the rules get changed.
The rules in the latest ISU documentation may be much more objective than the 6.0 guidelines, as long as they're in effect, but they're not written in stone and remain subject to change.
And the grades of execution are based on detailed guidelines but ultimately each judge's subjective evaluation of each element.
IJS or not, it is still a very corrupt system.
Subjective, as noted above, is not the same thing as corrupt. Totally honest individuals will sometimes differ in their perceptions and will often differ in their opinions about what's most important.
No system is corrupt in and of itself. Any system can be used corruptly if the people using it are corrupt.
The PCS will always be subjective. Perfectly honest judges will often disagree with each other on just which of the very good skaters was very best, or even when they agree on who, they might disagree on how much better (on a scale of 0-10 with quarter-point increments). Subjectivity without corruption.
The skating community as a whole might determine that it's better for public perception to be generous with judges using the top of the PCS scale especially at the Olympics than to be stingy with the scores, focused on the negatives more than the positives. So the use of the 0-10 scale might shift in the direction of using more of those higher scores for the very best current skaters who really stand out even from the next best. As long as the decision to encourage use of higher scores is based on principle and not on the specific skaters who would receive them, that's recalibration, not corruption.
Any individual judge or group of judges might also be corrupt. That's an unfortunate fact of human nature. The hope is that by giving objective base marks for technical elements and by breaking down all the subjective decisions into separate scores by element and component, so that scores do not equate to votes for placements, there will be less incentive for judges to act from corrupt motives and less room to control the final results if they do.
It may or may not be successful. Watching from the outside, we're not really in a position to tell the difference between corruption vs. decisions we disagree with, under any judging system.
