Anti skate is not necessary IMO.
It varies with the complexity of the music, off center record hole, and offset alignment type.
It is a moving target that can never be completely compensated for.
Also the stylus vibration is 3 dimensional, and there is not significant asymmetric stylus wear to worry about IMO. Anti skate is the least important part of the arm alignment. Dust control, arm setup, and clean records, results in long stylus life.
Try listening without anti skate. I use no anti skate, and do not have any inner groove distortion on almost 100% of my 2000 records.
