Do drivers are bragging about their engines. The first driver who majorly sucks on the starting line and has crappy tires but has a really good 350 in a ZR1 might go 13.2 The other driver who gets really good 60-foots, has his/her tire configuration just perfect but has a so-so 350, can run a 12.8.
Sounds like a line of hair splitting to me.
ETs can be the best way to measure overall performance there is.
Sure some exceptions can be brought to bear but there's many more exceptions that can be added.
Why even the effect of the moons gravity has an effect and the
imperfections on the asphalt under the right rear wheel. There
could even be a mosquito hit the windshield and slow it down.
Same driver running two different cars on the same night could even have
different wind conditions, a huge fly hit the windshield plus the major effect of 0.01oz of more fuel in one car vs the other. gezzzzzz
Seems like an exercise in futility to me.
A huge amount of meaningless exceptions can be added to dyno derived HP numbers too but I won't go there right now.

HP numbers are a fine metric but so is how many dimes you have in
the change holder. Being able to wave bye bye puts the "P" in performance. It's all together a better metric whether it's SAE or standard or pure air guitar corrected numbers.

Depends on the quality of the eye looking at it and the ambient air quality that the light goes through. But it should be SAE corrected air quality else
it's all for naught. And one should use proper wide spectrum light to test with and of course the angle of reflection should be at 90deg +/- 0.0000001 deg or the error will be so great that all bets are off.
Which is the better car?
1. 10,000 rpm V8
2. 502ci V8
3. 1800lb with driver
4. first over the 1/4 line

Answer: depends on which one I'm sitting in and Voltage measured at the spark plug of course.
Any hair that is split can always be split again until it looses meaning.
