Technics SL-1200G Anti-Skating

I used a Feickert Universal Protractor to align my Ortofon Quintet Black cartridge.  Instructions are to set anti-skating to zero, but it never says to set anti-skating to Technics specifications, so I left it that way.  At record start, the stylus would too often stake a little before it set into a groove.  

I decided to set anti-skating as recommended by Technics and the stylus stopped staking at set down.  As far as I can tell, all other settings are fine - and the music sounds great.  

Any other 1200G users that leave anti-skating at zero.  If so, why?
I set my anti-skate at about half for the Delos.  1.75 tracking force.  just below 1 on the anti-skate.

Instructions for what? 
Surely when you set-up everything the anti-skating must be at ZERO, but after set up is done it must be the same as the tracking force, slightly lover if the stylus is MicroRidge and related. 

If the tonearm is "12 inch like Thomas Schick there is no antiskating at all for such a long arm. 

But with your 9.5 inch tonearm antiskating must be adjusted. 

You can always buy a Hi-Fi Test LP to adjust antiskating, there are 4 bads to do that. Read about it, it's a great tool 
Instructions for what?
Feickert's instructions for using the protractor.

Thanks for the Hi-Fi Test LP link.  I'm going to guy the LP.
