The only point to overhang and pivot to spindle distance and offset and such is to help you get a starting point to better align the stylus to the appropriate null points on the curve (Lofgren or Baerwald and such). That's the purpose of these things. If you don't take the pain to set them exactly, but still manage to somehow align the stylus appropriately, I will bet that you have inadvertantly gotten them very close to where they should be.
But why take that chance and make it more difficult for yourself? Set it right the first time, then listen to music.
