Front Derailleur Adjustment

This one is going to be hard to explain, but here goes... Adjusting the front derailleur, Shimano 105... If I follow the Shimano instructions, I get weird trim results. First, I disconnect the cable, and set the lower limit for 0.5mm clearance against the inner guide. Next, I reconnect the cable, just barely pulling out the slack. If I do this, the chain throws over the large gear when I shift up. I can stop that with the top/high limit screw, but that makes shifting into high really hard, and I lose trim altogether - classic "cable too tight" symptom.

I can loosen the cable and get trim back, but then I have to move the lever when shifting into high until I hear THREE clicks, or I don't get trim! What am I doing wrong???
