Rocketman, I mean NO disrespect to your work and I certainly don't doubt math and physics. But as we are human there is not much quantification that can overcome confidence. The confidence of "feels right," whether it should, or does, or is simply believed because we like a feature is a very strong advantage. With almost 20 years in Pro Racing I see it everyday. Driver confidence will trump ( or ruin) the measurement of a set up the majority of the time. Of course it all needs to work to get the true last percent but most of us aren't 99 shooters anyway. Objective, though far more frustrating for the crew, can be just as valuable as subjective
