Alina, Adelina and Mao Asada had the most difficult programs back than (for their time). Skater-A.
Zhenya and Yuna had slightly "easier" jumps and ladings were not perfect, but both had higher PCS skills and likable programs. Skater-B.
Alina and Adelina had nearly perfect skates of their lives. Skater-A type wins. Mao had a meltdown and could not handle all her difficulty. Skater-A went all-in for a risk, but could not handle all the difficulty.
Zhenya and Yuna had less difficulty and were hoping for their reputations and high-PCS. However, their landings were not perfectly clean, therefore even their high-PCS were not enough against clean'ish Skater-A. Skater-B loses. Very transparent and understandable. "Sport principle applies" as they say.
Skater-A with biggest (and risky) difficulty always should win even if his/her/their PCS are not perfectly superb. Skater-B with less difficulty could only win if goes very clean AND opponent Skater-A goes so messy that obviously this attempted high difficulty is just unprepared and not ready yet (if ever). We seen Medvedeva once wining gold with a fall over other clean'ish high-PCS skaters. We changed the rules now: -5GoE and stuff. Now it is too risky to fall on difficult jumps, thus skaters are more motivated to skate clean with easier jumps. However, those who still want to risk are still having a possibility to push difficulty and boundaries of the sport. Unique talents, high difficulty tricks (unreachable to the rest of the field), risk and drama. This is why fans are attracted to sports.
Fans are discouraged and disappointed at
"I won gold because I had no quads, but more transitions". Karma is a ***ch. Look at the low-popularity numbers of FS in North America now (tv-viewership is going down, number of students are low, coaching FS is not a prestigious job any more), and compare with the current high-popularity of artistic gymnastics (where American WAG girls have the most amazing difficulty in the world, btw). Fans don't like corruption and want fair medals, otherwise they stop following this sport.
