I've noticed a phenomenon in syllabus levels of ballroom dance competitions where a couple (or a student, in a pro-am situation) will make several cuts in competitive events and as they get closer to the final, their dancing changes.
Their dancing becomes MOAR.
MOAR ARMS.
MOAR SMILES.
MOAR HIPS.
MOAR BIG.
MOAR DANCING.
And this is generally unfortunate, because the dancing that they had done up to this point was the dancing that made them make those substantial first cuts.
The thing is, in the lower syllabus levels, you don't know how to do better dancing. You don't know where to put the more into your dancing to make it even worthier of marks, awards, and finals.
So, you end up putting energy into your arms (and they get disconnected from your movement), or you put more pep in your step (and you get off time with the music, or you bump into your unsuspecting partner), or you emote so much you frighten the otherwise unflappable judges.
Doing more is not what you think it is.
In other words, you start dancing worse.
Your dancing is lovely. It's what got you into the quarterfinal, semifinal, and final. Stopping doing something different! (Smiling moar is always a good choice, though.)
