Ok, I changed my country to the US at the Nike+ website just so I can get to the blog widget. Here's my last run (Flash needed):



The graph show speed on the Y-axis and distance on the X-axis. I tried to run the first three kilometers at a fast pace, the next two rather quickly and then jogging the last kilometer. When looking at this run on the Nike+ site it shows that much better than the widget does.

You don't have to update the country to US in your profile (although I did), it seems sufficient to just change the country in the bottom left corner of the Nike+ website.
