I am running WPT in a private instance with video capture enabled. What I am seeing is that for a simple site like www.apple.com/? I am seeing Visually Complete times less than the Document Complete times (see attached doc). Maybe I am misunderstanding the defn of these two metrics - is Visually Complete an additive metric on top of the Document Complete time? This does not happen all the time but does for some of the sites I am testing against.
If Doc Complete represents the time for all the initial data to be downloaded to the client, then I would render to say that visually complete would come a bit later.
Appreciate any help understanding this.
