Body style and wind conditions will play large factors as well….a low slung car with low frontal area and a tail wind will obviously mph higher …
Not an exact science by any stretch!

I agree but believing dyno numbers between different shops is often way off, like different flow benches.
My now retired machinist had on old dial dyno, engines "ran the numbers". A shop down the road with a Superflow the same identical combination engine would always be 50HP more. He eventually took over that shop(owner died in a racing crash) and it took him quite a while to calibrate that dyno correctly to read correctly.
