1 - I was tempted to give it a 10, but since we could have walked away with 10+ gold medals easily but lost some important chances, ending up with 7 gold medals, I will give it a 9 out of 10. Still, the best Olympics ever for Brazil, no question about it. But it could have been even better.
2 - There has never been an official goal, but the unofficial goal was to reach 20 medals and we reached 21. So, I believe everything went well, maybe even better than expected.
3 - The biggest surprise has to be a bronze medal in tennis. It's not like we didn't expect a medal -- we did, but with Soares/Melo. Stefani/Pigosi winning a medal was not part of anyone's plans.
As far as disappointments go, volleyball/beach volleyball with only 1 silver medal has got to be the biggest villains. But maybe surfing and skateboarding could also be seen as disappointments. We expected 2 more medals in surfing and at least 1 gold medal in skateboarding. We could have earned 3 to 5 more medals in these sports, but our athletes fell short.
4 - Artistic gymnastics will be the sport that will receive the most funding, I'm sure. It has received lots and lots of money in the past, but now it will be even more. Our junior female gymnasts are not good, though, so we need all the money in the world to help them grow.
