I own an SME V and Doug's explanation above is what I experience. I manually lower the arm very slowly into the lead groove, rarely if ever allowing the arm to leave the cueing support. Once the stylus hits the vinyl and moves into the lead groove, I finish lowering the cueing lever. I use very little anti-skate force and my stylus rarely skips.
Another issue with the SME tables is the washer placed under the LP at the spindle. This raises the LP above the surface of the platter. The record clamp then pushes the LP down (at the edge of the label) as it is tightened resulting in better record/platter contact. However, the inner part of the LP, usually the area after the last lead out groove is sloped up toward the spindle (because of the washer) and this results in the stylus traveling "up hill" at the end. I am not enough of a physicist to know if this effects anti-skate forces.
