From my 2002 Winter Olympics blogging:
Judging Skating: An irony of the figure skating pairs controversy is that one of the flagrantly biased NBC announcers, Scott Hamilton, was the beneficiary of one of the most rigged decisions in skating history. Coming into the 1984 Games, Scott had been World Champion three years in a row. Everyone knew that if he won the gold, the personable (and heterosexual!) American would be a great ambassador for the sport. So, even though at Sarajevo Hamilton was sick and skated a weak final program, blowing off two triple jumps, he still was handed the gold.
Similarly, Sale and Pelletier, the supposedly martyred Canadian pairs skaters, were only in gold medal contention because the judges decided to not penalize justly their catastrophic double fall at the climax of their short program.
I sort of sympathize with this "cumulative" approach to judging, which tries to lessen the general problem with the Winter Games, which is that it's damn slippery out there. Thus, too many events turn on almost-random mistakes rather than on talent. The skating judges try to smooth out the results by voting for the competitors who have shown themselves the best over the years. Of course, on the other hand, that lends skating its aura of bogusness.
