But do you know Skater Y earned more points or simply received more points?
If you watch a basketball game and a foul is called when one didn't happen, it's probably just a bad call. But if the referee continues to call fouls against one team when none actually happen, the other team argues, the tv crew shows the replays, and the audience can see that something is not right. The same in soccer with a bad handball call ... one might be a bad call, but if it happens over and over again, obviously the referee is corrupt.
At Sochi, all of the suspicious tech calls, GOEs, and PCS scores happened in much the same way. Except nobody complains until a month later, the tv crew does not show the replays and examine the calls, etc. All they did was trot out red herring arguments to defend the results, regardless of what happened on the ice. The end result was most people feeling that what took place was not right, but they could not put their finger on why it was not right. And when that happens, they get frustrated and tune out.
