You are missing the point. My point was not comparing Europeans with worlds, or comparing the results from two different years from worlds. My point was that it is not so rare that someone would have one bad competition; one off when the things just don't work. You said that it is rare, I provided examples, you said that it is rare in dance so I provided examples with dancers. It is not so rare. The excitement/nerves/adrenalin just can mess things up.
