A. I also prefer COP.
As you already know, COP was developed largely against "cheating" and "bribery" among judges - particularly between French and Russian judges. Those cheatings really demoralize skaters as well as disillusion fans.
COP is not perfect, and human nature the way it is, determined cheaters always find ways to cheat; however, COP is more objective and analizable and therefore minimize opportunities for cheating.
B. I definitely agree with three - Dance, Men, & Pairs.
C. I don't necessarily disagree with Alisa's gold, and here's the nice thing about COP - it's so much easier to provide the reasons. Caro skated clean but her jump layout had lower base values; her spins had lower levels, etc. Alisa's wobbly landings/fall received appropriate deduction and lower/nagative Grade of executions. Alisa won SP and Caro won FD, but Alisa squeaked by by .12 points. I can live with that result.
In fact, it was such a close call that I can live with Caro winning over Alisa by .12
These athletes pour their heart and soul, and hard work into the sports they love. To me, any system that promotes less opportunity for cheating wins by wide margin. If creativity is sacrificed as a result, that is an acceptable liability to me. Although I strongly disagree with the notion that COP stifles creativity. It's true that all the requirements may seem restricting. But the stricture forces you to be more imaginative, and hence creative. You just have to be diligent.
