It also depends upon how educated your judges are. The more educated they are the less flash necessary. The less educated the more flash and sizzle wil catch their eye thinking you are doing spectacular dancing, even if you're not. The best thing to do IMO is dance what suits you best, to the best of your ability and let the judges form their own opinion.
Thats so accurate. And its true in everything, the less deep the knowledge, the more sensitive to superficiality they are.
And yes also on the approach. The only way to approach any art is to treat it as if the audience (which is all the judges really are) is none of your business. Do your thing as best you can to your standards and let the chips fall where they may.
