So, my last comment was me being a vaporhead. It turned out I used the wrong benchmark tarball.
After having done the tests on Grav2 and Grav3 instances, on both Focal and Jammy, the results are all over the place. Dave agreed offline to re-run the tests on the Pis with 100 runs rather than 10 to hopefully get rid of the noise, while I do the same on the AWS machines.
