From an email sent to me from a leading setup authority:
"According to my Japanese books from 80s the Effective Length of your Excellent Arm is 282 mm (pivot to stylus). The manufacturer's Overhang is specified for 12 mm.
This is not correct. The calculations based on Prof. Baerwald formula give Ovhg = 14.5 mm. So the distance from arm pivot to platter spindle should be 282 - 14.5 = 267.5 mm."
One of the overlooked tuning features of this arm is the tightness of the dial used to hold down the arm.
