One thing that's interesting is that the Navigation Timing API available in modern browsers varies from being wildly incorrect to accurate, depending on the browser. In a quick test on my Mac, Firefox 13 showed an incorrect result (basically, the same issue as WPT and Gomez - almost immediate TTFB), while Chrome 20 correctly detected the 10s TTFB.
