The whole dealer episode was funny and sad. I told them I wanted to talk to the techs about how I wanted the alignment set. They said OK but I could only be in the shop for a couple minutes. I went back and talked to the techs, they didn't seem to total understand but I was told I had to go back to the waiting area. About 30 minutes later they called me to the shop. Apparently the techs didn't understand alignment adjustment at all so I spent about 15 minutes with them explaining how everything worked.

I think that the usual process is "twiddle the bolts until the machine shows green" (regardless of where in the range any of the numbers are, green means "good and all done") And 99.9% of folks won't notice or care.
