It’s not ideal or universal for any TT. In my case I had to set the VTA level higher than suggested due to the fact that lower border of VTA adjustment was limited by the bottom of tonearm lift base and at the time when correct (parallel) VTA level was set the bottom of lift device was actually touching the arm board and didn’t move whole way. In simple words, some TT has unique design and mechanical specs which could make difficult implementation of the program.
