One possible error in ground speed measurement: the tire likely grew in diameter as it spun faster. I don't know how large the effect is here, but it's worth checking or noting.
- speedgoose 6y agoTrue, it could explain a small difference. But here the difference is huge, especially in terms of RPM.
- jml7c5 6y agoYeah, it wouldn't be enough to make such a huge difference. Nor would it explain the different RPM. Just wanted to note it for the sake of completeness.
