I published a "how we test GPUs" thing a while back... not sure many people bothered to read it, let alone actually doing any testing. It's very much a situation where the effort required (to share and demonstrate how to test) versus the benefit (people being able to copy what we're doing) usually doesn't make it worth our time to share extended details. It's literally the 1% of the 1% (of the 1%) that might actually try our saves and benchmarks in my experience. LOLCompletely irrelevant (somewhat I guess) it would be nice if you could share the save files from your tests like PCGH does. Cause testing the same area isn't the same, your save file may behave differently / different time of day / npcs etc. It's just a suggestion for future reviews.
The reality of benchmarking games is that, for anything that doesn't have a built-in benchmark, most outlets just find something that seems to work fine for what they're doing. And since no benchmark is perfect — you can't represent the entirety of a game with a 1~2 minute benchmark run, or even a 30 minute run — they're all just approximations regardless.
