Maybe a rocket scientist can chime in?
I was only try to learn this for those track days and possibly drag days. A friend of mine is try to create a little get together amongst friends and see who's the fastest. Of course just for fun and on a track. But rocket scientist... maybe, but I think that its just time consuming and tedious like dynamatting a trunk or full detailing a car
