RE: Animated pages and visual metrics
Yes you are correct. The page is mostly completed by 4 seconds, but the animation throws it off. At the 14 seconds is when the MP4 gamer glory begins to load.
See this info in the WPT documentation: https://sites.google.com/a/webpagetest.o...peed-index " This is the original mechanism that was used to calculate visual progress when the Speed Index was initially created and still works well but there are some cases where it has problems (video playing on pages, slideshows animating or large interstitials). It is very sensitive to the end state and calculates the progress based on the final image. It is also only measurable in a lab and relies on video capture being possible."
