I am such a negative nelly today....
but these "graders" are all subjective for the most part...
it is an "opinion"
and we know the expression....
yes, some trimming maybe obvious, where some is not.......
can anyone truly , I mean truly tell if a card has been trimmed???? under mag a depression of the side in relation to the rest of the card, but his maybe also mimicked quite possible by the machine???
point- grading is truly a "subjective" art although a scientific objective approach maybe utilized....
these graders are wrong I would say 20% of the time...
a true scientific analysis..........statistics....regression models.....and sampling would have to be done to estimate the true error rates and mistakes in general on 3rd party grading....
I would love to see the deviation of the sample or the bell shaped curve on either end
