I'm sure your dealer is right. A friend's P1 (also with Bias 2) does the same thing. That doesn't necessarily mean the antiskate is set too high, just that the cueing mechanism doesn't provide enough friction to keep the arm in place against the outward force exerted by the antiskate setting. FWIW, my friend set his antiskate to its minimum value so the cueing worked more accurately, and with no drop in sound quality or tracking ability.
