Anti skate question for Rega P8/RB 880 arm

I just replaced my cartridge with the same one I had (Van den hul MC-One Special) and I am getting conflicting advice on the anti skate settings. It is a Rega P8 with RB 880 arm. Rega says tracking force should match anti skating, Van den hul box says 1-25-1.5g tracking force, but only .2-.4 anti skate, and I have a tru-lift automatic arm lifter whose owner told me the anti skate should be 1/2 or less the tracking force on a Rega. That was after the arm was slipping off the lift bar. I moved it to about .75 anti skate. Before that it was set for 1. He was even saying you don't need anti skate.

Please don't tell me to experiment and see how it sounds. It is set for 1.43 g tracking which I don't want to touch. Thanks.
