What is you tonearm’s Maximum Distortion?

I’m trying to make careful measurements, but only using a metal ruler - nothing fancy - and plugging the measurements into the vinylengine “Overhang Shift Calculator”.

Right now I am using the HiFi news test LP protractor, just because it is handy. Does anyone know what alignment it is?

And I am mostly curious what the figures are for the tonearms of folks like you? Just because this is a new area of exploration for me and it might help me get a better overall concept of what is going on and how important the numbers are.

My ears are pretty good (professional orchestral musician who is a bit obsessed with tuning perfect intervals, including overtones). But my listening room has never been really ‘tuned’.

Does anyone have their tonearms’ figures, re: max. distortion % and max. error degrees?

Good point, lewm. I will reword my question:

Does anyone have the theoretical figures for your tonearms’ maximum distortion % and maximum tracking error degrees, based on the vinylengine Overhang Shift Calculator?

Most of us understand that measurement is the only way to actually know what is going on. Which is a theoretical argument in itself, seeing as probably no one who uses this site with any frequency has the equipment to do such measurements.

I am just interested in others’ numbers, in the vinylengine calculator.

Has no one here used it, or is it rather that no one feels obliged to post their numbers? Just curious.

Thanks petg60 and Raul, much appreciated.

Thanks to those who posted their figures. It is much appreciated.

Zenith error should be able to be resolved with a compensatory alignment angle I assume. Ears seem an adequate way to hone it in, once an appropriate alignment protractor is chosen and set to (although time consuming).

Time for us to lobby the cartridge/stylus industry for zenith error specs!
