And the winner is...
The exam for the bronze medal went rather well for us, as far as I can judge (i.e. I did not fall during the choreography). The speaker only announced the names of the actual candidates, so when I heared "And now, for argentine tango, presenting a bronze medal program, Ms V... and her partner", I remained on my seat for a while, until the speaker called us once again. By chance, another couple was presenting the same medal, so we were not the only couple clumsily walking on the floor in front of the wild crowd eagerly scrutinizing our mistakes.
The judges give two notes. The first is about respecting the tempo, the second is about general technique. The sum must be over 10/20, and a tempo note under 3/10 (as well as a technique note under 4/10) means you fail the exam. I think it is somehow unfair for the woman, as if she happens to be offbeat, it is entirely the leader's fault. If I were the judge, I would award ourselves 6/10 for tempo and 3/10 for technique (exam failed), but firstly the judge happened to be our own (ballroom) teacher, and secondly the other couple was even worse. So, my partner still has hope to gain her third bronze medal.
We didn't dance a full tango piece. For a medal exam, the dance lasts only one minute and something. We asked the organizer to make this "something" a bit longer, because in our choreography the ending pattern comes only after 1mn 40. Agreed. But the other couple whose own ending pattern duly came after one minute, wasn't prepared for this and had then to stay still watch us dancing. The same funny thing repeated later during the viennese waltz exam: a gold medal candidate danced alongside a silver medal one, finished much earlier (because his program was much more difficult) and had to make endless salutations until the other couple finally ended their own simplier but longer program.
