This 'tune' as I call it is the difference between the toes being within spec and hitting the sweet spot for your particular car.

Use this calculator https://robrobinette.com/DIYAlignmentCalculator.htm with parallel strings and You wil have a very good 4 wheel alignment DIY tool.
I am using the calculator with a couple of wood strips to keep the strings parallel each other and a good digital caliper for measurements. The results are excellent: ALL of my cars drives straight and no abnormal wear on tyres (front and rear). A nightmare everytime I have been for a wheel alignment in a garage. Hope this helps
