The "controversy" was not a failure in the system, but a judging error. Those happen all of the time in most every sport. If it was such a bad system, figure skating and ice dancing would not have switched to it recently.
There were several controversies, at least one of which was a judging error. Others happened *due* to the judging system, rather than in spite of it.
The biggest problem in my opinion is that they define what is a "best possible" routine. In the individual finals all the top gymnasts compete with a 10.0 start value, so the *only* difference between them is how many deductions they get. For example in the horizontal bar men's final, one of the officials commented:
"Nemov had a spectacular routine. But as a judge, you must see in the release at the beginning of the routine, there is a slight bend of his knees, which is a deduction," he said. "
It made not a jot of difference that his routine was more spectacular and more difficult than the other athletes, the value is 10.0 (the maximum) and after that all the judges do is deduct a point for this and a point for that. This sort of judging system instantly kills any possible further developments in a sport, if a routine is "as good as possible" why would you want to make it "better"???
I think the reason these systems are introduced is that it gives the judges something to hide behind. They can say "he got 9.387 while the other guy got 9.365, so the first guy won". The judge doesn't have to explain why he thought one athlete was better than the other, he just says "i deducted 0.1 points because his foot was turned out by more than 5 degrees when landing", but is that really what makes one gymnast better than the other?
The whole of the gymnastics (and incidentally ice-skating) world seems be full of complaints about their judging system. A fairly typical comment I found on some gymnastics news was:
"There wasn't a gymnast in the audience who didn't want Nemov to win," Ziert said. "But the rules didn't allow him to win. The judges gave the correct score, according to their rules. But the audience didn't want their rules, and coaches don't want their rules. But we've got their rules, because the judges control the sport."
Sports that are judged should be honest about it and not pretend to be precisely measured. Maybe for something like diving you have such a limited set of things they can do that you can measure it with a computer (ie angles, amount of splash, rotations, etc.), but for something like gymnastics or dancing, any complicated system will just increase the chances that the "wrong" person wins...
