And theoretical setup is a useful guideline, but with driver brain, habits, preference, and skills as the largest of variable of them all... It can really only be finalized on the field, with equipment, talents, and resources, and over many trials to get there... So I can't really say yay or nay on your inquiries at this time... It's other half of tuning is on the seat of your pants.
Even things like full, half, or empty tank of gas will require changes in suspension in an ideal world... So... Numbers start to get really confusing when there are 1000 other variables. Great guideline, yes, but from there, you need to play with actual feeling of real driving. After all, it takes the best engineers a full year to figure out the right setup for only 17 tracks on an F1 cars, and half of them still not close to perfect on the field each time... We've got way more than 17 places to go in our cars, and work without billion buck R&D.
