<p>[QUOTE="physics-fan3.14, post: 3625364, member: 19165"]You are absolutely correct. There is whackiness in grading. There is variability from the TPGs. There is inconsistency in the color bump. I really can't argue that. All I can do is take an average over a sufficiently large sample size, and find what the average result is (hopefully, over a sufficiently large sample size, this sort of thing diminishes in significance). I'll also say that, for the most part, the wildly toned coins make up a small percentage of the overall GTGs, so it doesn't distort the average grade discrepancy as much as you might think (except for your intentional posts, of course <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie2" alt=";)" unselectable="on" unselectable="on" /> )</p><p><br /></p><p>There is more grade discrepancy between CT and the TPGs from AU vs MS posts than from color bump posts.[/QUOTE]</p><p><br /></p>
