After day 13, we have 12 more total medals, and 1 more gold than our pace in Athens. And with events that we could still medal, we could definitely surpass our total in Athens and at least (hopefully) tie our gold medal haul. So much so for China overtaking us. IMO, China overtaking us in golds only mean that, they've overtaken us in golds in their home country. Let's see how consistent they can be in London.
All in all, there were events that we didn't even win a medal where we've won some in Athens and it's so evident in Athletics and Gymnastics, and our medal total being still higher than Athens, Team USA is doing a fantastic job in Beijing.
