Anti-skate setting on Graham 2.2

Hi All - There's a lot about setting the antiskate, but not much on the following question.

Here goes - I've set up the Graham arm (VPI TNT w Kleos) and VTF and overhand ets are spot on. I then use the Cardas vinyl setup disk to set the antiskate by using the cool blank test track in the middle of the LP. I've set the antiskate so the cartridge stays in the middle without swinging out or in. Seems spot on to me.

So, the question is - upon cueing the arm up or down, the arm will swing towards the outside of the record - should this happen?

Because the antiskate weight counteracts the centripetal force towards the spindle, then the cartridge should swing outwards when not loaded by centripetal forces- so this behavior makes sense to me.

But, I've yet to read anywhere that this actually what should happen - that the arm should swing out when cued. In fact, I mostly read that that the arm should drop straight down when set to play a track - if so, then it seems to me that the antiskate can't be doing much.

So, I'm hoping someone can confirm. Thanks !

I have a Graham 2.2
Start with it set at the mark corresponding to the tracking force as Graham suggests.
If you can clearly see the cantilever with a good flashlight head-on, set anti-skate so that the cantilever does not move L/R when lowered in a groove. It is important that the cantilever be correctly centered so that the coils are as nearly as possible in the center of the magnet fields. This also aligns the L/R edges of the stylus in the stereo groove. The Graham has a very precise set-up gauge, It would be a shame to waste it by not having The cantilever straight in the groove. This does not preclude that in some setups the stylus could be geometrically centered with zero anti-skate.
