Hi, I am wondering how we should interpret visual metrics such as speed index when a page has lots of animations?
An example will be the Amazon home page (https://www.webpagetest.org/result/170713_TR_1MZQ/)
They have a large image in the middle that auto scrolls. By looking at the video, I would say visual complete is at about 4s when the sign up button pops up. But because the big image keeps changing, the test considers the last frame to be at 14s. This means that the visual metrics are being overestimated. Is my understanding correct?
