Marc, how about this. I fully support and agree with Kirk's fear of setting weights by on track performance.

On the other end of the spectrum, I also agree we can't completely ignore it, nor would it be possible to (we are human, and what we see and observe matters to us).

I think Jake put it this way, and this I agree with: observed on track performance should be a trigger for us to take a harder look at a car, or what the process "spits out" for that car.

I see that as a fair balance between the two extremes. Your thoughts?
