As Dover suggested, most internet gurus have recommended about a 50/50 distribution of the VTF between dynamic and static. However, I do find that the venier setting for VTF on my FR64S is accurate to within +/-0.1 gm, if I take great care in zero balancing the tonearm with the venier set to "0". But most of the time, I am too lazy to fret over that. I have never done the experiment carefully enough to say that I can confirm the belief that mixing the two modes of setting VTF is beneficial; I just do it that way.
