I'm happy to see this exist; I've considered putting together something similar using the data I compile for https://sbc-reviews.jeffgeerling.com/ - but it's surprisingly complex.

One of the hardest things is settling on specific tests, and ensuring tests are run in an extremely standardized environment. I do my best, but a test lab I am not.

It's good to have a quick way to get relative comparisons, even if imperfect.
