I have had some similar experiences and gotten a bit worked up about this sort of discrepancy. Ultimately, even assuming the best graders, grading is a practice and not science. Whose knows you could submit to PSA again a month or two down the line and get a "7" from them too (or a "6" or an "8" ?)
