* a script was already minified and offers a relatively conservative minification estimate (our two
* primary goals).
*
* This audit only examines scripts that were independent network requests and not inlined or eval'd.
*
* See https://github.com/GoogleChrome/lighthouse/pull/3950#issue-277887798 for stats on accuracy.
