What angle should I set the VTA on my VPI turntable?


I can't believe after all these years, I am asking such a basic "analogue 101" question, but here it goes. I own a VPI turntable that has a "VTA on the fly" knob.  I thought the best VTA setting was for the arm to be 100% parallel to the record surface.  

However, based on some research, I am not so sure that is correct way to set the arm to achieve optimal VTA and correlatively, optimal SRA.  Not sure, ... but I think I have to raise the pivot side of the arm.

Any advice would be appreciated. 

Thanks.

I’m one of the contributors on vinyl asylum that posted pics with SRA measurements from my USB camera. The last time I did this I was attempting to set a Soundsmith Sussoro ES Mk 2. Peter L. chimed in and explained that there’s a tiny facet that determines the contact geometry that’s practically hidden from view, even with a USB camera. I could barely make it out, but only with the stylus raised, not in the groove. Seeing the futility of this effort, I went another route, starting with parallel and then fine tuning with Analog Magic. I am NOT one to fine tune VTA/SRA for every record and my SME doesn’t have that provision anyway.
