 Do you mean [https://github.com/GoogleChromeLabs/wpp-
 research/tree/main/cli#benchmark-web-vitals benchmark-web-vitals]? It
 should work on Windows, as long as you have npm installed, same as using
 the build tooling in WordPress core or Gutenberg. I don't think you'll
 need to troubleshoot the tool. It won't be needed on an ongoing basis.
 Otherwise, you can use Chrome DevTools with network emulation set to "Slow
 3G" and then look at the LCP metric which shows up in the Performance
 panel. This will be the same result. The benefit of the benchmark-web-
 vitals tool is that it can do many repeated tests and then compute the
 median result, which helps to eliminate the noise and variation that can
 happen with a single test.

 Aside: As part of #63018 I'm planning to extend the benchmarking for check
 the impact for inlining more minified CSS on initial page-visits versus
 subsequent page visits with that CSS instead being in cached external
 stylesheeets.
