I would like to point out that I don't think about things in quite this depth when at the track
As most of us are merely in the business of use, and not design, I would suggest it's more important to have a good understanding of the cause and effect relationships rather than the why, i.e. have a general feel/understanding for how changing various settings will affect the car's handling.
Even what appears, on the surface, to be a simple problem can often become complex very quickly if you try to fully understand what is occurring. I posted my thoughts, which may well be way off the mark. Even if some of what I said is there or thereabouts I am sure there is still much more to it, assuming anybody understands it fully at all. After all, there are many things in this world that we are still unable to truly comprehend; plus the nature of engineering is to often describe real processes with an approximate equivalent that shows good correlation.....
