You've got to remember that with level calling, the tiniest detail could be off and it drops it down a level. If the difficult position they go for is a Biellman, and Tessa is a fraction of a second too late bringing the blade to her head - boom, down to level three. One of them grabs the blade a little too late in the twizzle - boom, down to level three. They slip off an edge from outside to inside in a footwork sequence - down to level three. More than any other discipline, the level calling in ice dancing really crucifies mistakes.
