Anonymous. I can see that your experience within the world of competition dancing you have a bit to learn. First , if you were a judge and knew a couple on the floor they would have more chance of being seen. I can tell you here a few years ago a dancer unheralded but with a higher world ranking than thoes that did, never even made the final.This event was also to choose the countries represenative for the following year. The guy who won it publicly anounced that he would stand down in favour of the other. He now living and teaching in the US and got himself extemely disliked for being so honest. A almost identical thing had also happend a couple of years earlier.The message here is make sure that your presence is known by having a couple of lessons with those who are going to be judging.
I am told the formular is four. To even get into the finals in major competitions you need to be having lessons with four of the panel of judges.
I was also told that this is the system that exists at this present time.
You cannot change the system. Therefore you must use the stystem to your best advantage if you are going to partake . It's a pity but there it is.
Just to finish. A judge told me that in a National competition in one of the early rounds . To his horror as the couples were leaving the floor he saw the best couple in the country, he hadn't seen them, and hadn't marked them. It can happen. The can of worms is now opened.
