Tonearm Geometry and Setup


While this subject matter seems to be of 'crucial importance' for our hobby our discussion about this issue is fragmentary and split over different threads in our forum. As if we are talking about some 'abandoned child' that nobody wants. I thought that this 'child' needs its 'own home' in metaphorical sense or its own thread in the
usual sense. While tonearm geometry seems to be very 'simple' in mathematical sense there are many unresolved questions in the actual sence.
My question for the start of this thread is:
'why are we not free to choose the zero points on the record radius independant of the tonearm used?'

I thought that these were the product of the width of the record, which is a constant, the length of the tone arm, which varies, and the chosen formula [Loftgren etc] for producing the least distortion. This would appear to offer zero degrees of freedom so I must not have understood the question.
