There's a lot of other tests that reviewers have to do, depending on their audience. Video editing (Adobe Premier), 3d Modeling (Blender), a few video games across genres (maybe an Adventure Game (Tomb Raider), a FPS like Overwatch, a strategy game like Total War, and a simulation game like City Skylines), and a few other workloads (audio, programmer, CAD, HPC, etc. etc.).

So there's that, but also the time to write these reviews. And finally, you're trying to out-compete everyone and release the review before everyone else so that your website gets more traffic.
