It will, but it&#x27;s still a net win because Google&#x27;s not actually optimizing for time to load.  They&#x27;re optimizing for time to usability.  Moving all of the non-essential CSS out of the head and into a post-load request increases the total request time but decreases the time until the user can begin interacting with the page.<p>It&#x27;s still drastic overkill for almost everyone except Google, but it does make sense for their use case.
