    Field metric only, no WPT test run data.

    Note: Why can real browser usage metrics vary from test run metrics?

    Variance between your test run and real world usage is expected because a WebPageTest run uses a specific connection speed, and real world data spans all connection speeds. To closely match the p75 user in WebPageTest, try rerunning your test using a different connection speed.
