Question Alignment Analysis Help

I was getting some heal to toe wear on my Contis so I had the dealer do an alignment today. Attached is my report. While I understand a little bit about alignment, I am hoping one of the techs that hang out here, or someone else with some expertise, could help with an analysis.

Specifically, look at SAI and Setback. While not adjustable in themselves, even after the standard camber and tow adjustments they are still a bit out of spec. Only a few minutes, but still out of spec.

What does that mean to you?
Is the deviation so small that it does not matter?

Thanks.

they arent adjustable and really arent a big deal and arent affected by camber or tow adjustment. however, your front camber wasnt adjusted at all..probably because the tech was too lazy to drill out the stupid little adjustment nipples and do it properly. by heal to toe wear you mean cupping?

The front camber did change a little but I did notice too, that they were not really close to the target. You would think for $149 they would do it all. Thanks for telling me why they might not have done it. Maybe I'll bring it up next time I'm in.

Heal to toe: if you look at the tire from the side, you can see the rear (heal) of the blocks slightly more worn then the front (toe). Hence the term, heal to toe. It just makes the tire a bit loud. It's not real bad now but want stop the problem.

As to the SAI and Set Back. I know they are not adjustable but my concern was that if out after the alignment, that the car is bent slightly. If bent, is it of concern?
