Performance-monitoring tools like WebPageTest and Lighthouse report LCP. At the time of writing, Google has advised that an LCP of 2.5 seconds or less is optimal (http://bkaprt.com/rjs39/03-04), but future guidance may vary. The best advice is to shoot for the best possible score, since LCP can affect how your page ranks in search results.
