Sometimes, by fact quite often, almost all styles might be inlined. And then the "real" file would be downloaded, doubling the traffic.

So, what about

reporting used coverage
and if it is above some threshold (80%) - inline the rest
and somehow report that the original file might be downloaded in a low priority

Yup. I am testing used-styles on our project and efficiency looks pretty bad. Coverage shows less than 50% efficiency.

@zeppelinen - could you elaborate a bit? What does mean "coverage" in your case? "used" is > 50% of a whole CSS? Then it's all about the speed of your backend - if 16ms you can save my inlining styles matters for you - then it's worth. In another case it might not.
