Ah, very cool, thanks for sharing. I'm familiar with a lot of the tools for evaluating the performance of a single site (e.g., that I'm developing), but I'm pretty ignorant of the standard approaches for these types of larger scale benchmarking projects.
I actually wasn't aware that the site could also perform the test, but the Page Speed Insights Chrome extension is one of my go-to performance tools. The output looks the same, though formatted a little better in some places. The extension is nice though, because it lets you check private sites.
