As others have pointed out, DWTS scores have little to do with how real ballroom competitions are judged. At the risk of getting off-topic, here are some thoughts on why. While the announcers say that the judges' scores and the public's scores are given equal weight in the final total, those scores are arrived at differently. It isn't hard to see that the public has more influence on the result than the judges (it's a popularity contest). Without going into the details, there is little spread in the votes from the judges, so the last-place contestant doesn't get a much worse number than the first-place contestant. But nothing limits the spread of votes from the public, so the public's opinion influences the result more than the judges' opinion. That's how a contestant ranked highly by the judges can get eliminated. BUT (here is the point) it appears that sometimes the judges tailor their votes--and associated comments--to influence how the public votes. This means that their criteria are considerably different from those employed by the judges in real ballroom competitions.
