I am glad you got your information and that you can enjoy your triplanar as I do. But the way you asked your question it seemed to me and some others as though you wanted to know exactly what one setting on the circular gauge achieves “correct” VTA, presumably so you could set up your tonearm once for all situations. But the correct or baseline VTA setting of course will be entirely dependent on what cartridge you are using (and the vinyl and the platter mat). The markings on the circular gauge at the top of the pillar are simply there to provide a handy reference point, so you can keep a record for what works with what, which you evidently do understand. Sorry for the confusion.
