But the millions upon millions of graded cards out there are not altered to begin with. So the actual ratio of accuracy should be calculated on the number of Altered cards that were submitted related to the number that were caught. The millions upon millions of unaltered cards shouldn't be included in the calculation. This would bring the percentage way down from 99% accuracy to a much lower number, maybe 25%. Just a guess. That's pathetic reliability for a paid service.
