Dear @mijostyn : No, I did not but that was not the issue why posted VPI and I would like to know what HW was thinking when designed his tonearm with out AS mechanism.
Now, yes I like to put at minimum developed distortions by the roomsystem and I like to do it when exist some certainty that in reality " those " distortions are at minimum but in the AS subject it’s a losted " figth " before that figth begin. To many variables and " if’s " . You ca't have certainty of any " thing " that is constanty changing alomost groove after groove all over each one LP grooved surface where does not exist two different scores in LP’s recorded exactly with similar groove modulations at the same places all over the LP’s surface. We can’t really know if distortions are at minimum with that AS of 0.15gr. against none.
For now I don’t like to " figth " in something that defeats me before I begin against it. Just my common sense on this specific AS subject.
You are fine with what you have and me too with what I have and maybe just maybe the quality sound differences between that 0.15gr and none could be inaudible at least in my room/system and yes with my ears.
For me and taking in count all what I posted about it’s futile/useles to worry about AS. Today I’m really happy not to have be worried because that imposible to fix AS, yes that’s me and my opinion.
