I can't remember what the logic for that was. I think I was messing around trying to see if I could appease google pagescore on such a tiny page, and eventually I just gave up and left as it was.
That's quite an ugly optimization step. You left out the step where you inline the necessary CSS styles in the head that's why the unstyled page flashes up for a second. But as you use bootstrap, this might be a lot to inline and not worth the effort.
I'd say this is a case where you shouldn't care too much about a highscore :-)
