You may be surprised, .. the "grump" is a fairly smart guy. I don't know if he uses all the flow ratios and coef stuff, .. my cuz works there, I'll have to ask.
But yea, things have changed. In the 80's I was offered a job at a few NASCAR teams, .. now if you don't have a degree in engineering they won't talk to you, . no matter what you've done in the past.
