But his is not what happened here. Leveling the playing field between Yuna and Adelina would have meant inflating Adelina's PCS enough so that when they are both clean they have the potential to score similarly (Adelina's TES being offset by Yuna's PCS). What actually happened was that they gave Adelina more or less the same PCS as Yuna, which, combined with Adelina's higher BV, meant that Yuna could not beat her no matter what she did. In fact, Yuna would not have won even if she did 7 triples instead of 6. This is not leveling the field, this is giving an unfair advantage to Adelina - unfair since her skating doesn't (yet) warrant the kind of PCS that she received here. Yuna should have easily trumped her in every category of PCS (apart from TR, maybe), yet she didn't.
As a sidenote, Yuna's PCS here was also slight inflated, but this was necessary since they had already dug themselves into a hole with Adelina's PCS and couldn't possibly give Yuna lower marks - imagine what the backlash had been then.
Btw, this is not only about Yuna vs. Adelina. The scoring in the whole Ladies competition has been a mess, with inconsistent technical calls, dubious PCS (Yulia scoring higher than Mao is one glaring example), levels and GOE all over the place etc. I really hope they get rid of anonymous judging as soon as possible, so that if something like this happens again there is at least some level of accountability (the skaters themselves have no fault in this, they just did their job to the best of their abilities).
Did you not notice the same at GPF? Hanyu was given a sudden boost in PCS, double Sotnikova's, so his PCS was leveled with Chan. Hanyu used TES to beat Chan, much like how it happened here. Of course it is fair, whoever skated the more challenging program, more difficult elements, with better components, wins. For the first time, Hanyu competed without a handicap, a handicap that YUna's fans insist Sotnikova should bear. Without this PCS leveling, Chan would have a cushion of at least 2-3 botched elements over Hanyu, i.e. falling twice and still win, which isn't fair to Hanyu. It is the same at work here, Sotnikova is given a chance because it is not humanly possible to overcome a 20 point gap or add 2-3 more big elements to a packed and jumps-laden program. Kim's program wasn't a cakewalk, Sotnikova's best BV is only 4-5 points over Kim. So what does a challenger have to do to have a shot at beating these PCS-gifted and laden champions? Hanyu has to do 6 quads to bridge a 20 points PCS gap? Sotnikova has to do 3 trple axels and 6 triple combos? Therefore the top 3 ladies had PCS very close to each other, and it is up to the TES battle to secure the win. It is fair because a technically more challenging program takes greater skating skills, strength, agility, etc., to skate. Citius, Altius, Fortius, as the motto goes. Hanyu and Sotnikova fell so many times through their senior circuit before they finally manage to skate their programs clean, to skate them well. They paid their dues to skate harder, faster, better. Who else today can skate at their level of BV? So yes, their higher PCS is earned too.
As for Julia vs Mao, didn't Mao win GPF, even with a fall in the LP, due to higher PCS, even though Julia skated better, with higher TES? Mao's PCS advantage over Julia's was +14, with that kind of cushion, Mao could fall 3 more times and the GPF win is still guaranteed. So for Hanyu at GPF, and at this Olympics for Adelina and Julia, it would be humanly impossible for them to beat Chan, Mao or Yuna if their PCS gap remains unchanged.
It is also untrue to say that with lower BV, Yuna cannot beat Sotnikova. Just look at the Men's Olympics LP. After Hanyu botched his skate, everyone thought that Chan would win OGM. If Chan had skated a clean LP, even with a lower BV, he would have, well, the rest is history.
Higher PCS is a guarantee, it's points already in the bag. Higher TES BV still NEEDS to be racked up in the performance, to be earned through punishing training, through flawless delivery when it counts. Higher BV means greater chance of botching the skate, of falling, of making errors, so Sotnikova was taking a bigger risk than Yuna. If she wasn't good, she would have fallen and lost. Yuna could of course have raised her own BV to include say, a 3loop. That would be a greater insurance of her second OGM. She knew Adelina's layout, she could have up her game, as GPF showed that 20 points PCS cushion for reigning champions like Chan could vanish in an instance when a younger challenger like Hanyu stepped up.
