Your measurements do indicate rear toe out, but we're also assuming you setup a perfect square on the string alignment rig. Tear down your strings and put them back up. Do you get the same measurements indicating toe out, or are your measurements different than the first time? If your measurements aren't the same, then at least part of the problem is your process.
When you say you did your own alignment, what do you mean? did you make alterations to camber, toe, ride hieght, or did you only measure what they are?
I'd recommend checking your work with one of those big calipers that gives you total toe, or going back to the alignment shop and just having them tell you what your current alignment is.
Of the sheet you provided, your rear camber is more negative than most plots unless you're putting the car on track, and on slicks. Also from the sheet, for the rear it indicates more toe in than typical. Mine is set at 2.8mm total toe in for the rear, but overall I think you're looking for around 3mm total. Of course nothing is absolute, but if you don't have much knowledge in the world of alignments and you're not using someone elses "known good" alignment as a reference, probably should be closer to the "norms."
