I know this sounds counter intuitive, but have you tried using the two ‘outer’ grooves instead?
I’m surprised Pro-Ject utilized such a rudimentary method to set your anti-skate on this table......but....I have a Soundsmith Zephyr, and using Peter Lederman’s anti-skate technique, I typically have my anti-skate set for about 1/3 to 1/2 my actual tracking weight, or, when/where the stylus very very slowly moves towards to spindle.
May be worth a shot to try one of the inner notches.
