What is your to earl’s Maximum Distortion %?

[Header meant to be: “What is your TONEARM’S maximum distortion”. I have been reading many comments about Audiogon randomly (or not) putting in typos, and it seems this may be the case!]

I’ve been playing around with different cartridge mounting, as a Grace arm the plinth of my Lenco cannot be mounted at the recommended pivot-to-spindle distance of 222mm (closest it can get is 225mm).

My best figures in theory seem to be:
Max. Tracking Error: 3.51 degrees
Max. Distortion: 1.21 %
Average RMS Distortion: 0.73 %

This is with: P-t-s 225mm; overhang 11mm; offset angle 19 degrees.

What are your figures for your setup?
