Sliding force???

I accidentally happened upon an ECM LP with a blank fourth side ("Into The Silence")

and notice what happens:


Then I enabled and adjusted anti-skating to tame it:


I know ddk has designed his platter to provide a sliding effect to some degree, but I thought mine was excessive. Still trying to assess possible sonic effect.

Thanks for your very detailed explanation, Tasos. Very well expounded and it's quite clear to me now, re your AS device and how it works. It's good to know that you are getting good use from it, and that is a very good thing.
Here's more along the same lines from the Analogue Productions Ultimate Test LP

That Track 1, as it says, increases in amplitude over time, and the tone must remain clean.

The most important quote in there I thin is "Both linear and modulated groove velocity, tracking force, stylus profile and vinyl composition are contributing factors"

Thanks Ack.....I use this test record for several setup steps including AS. I listen thru headphones on this track and currently the signal stays clean, the last 4-5 seconds I hear a very slight distortion at that +12db amplitude. I have played with both the AS and VTF to see about eliminating it but no success yet. I'm not too concerned about it as again it happens right at the end. I check my Delos stylus about 3x a year under scope and it has no uneven wear......I think I'm good with it.
