Mara, ideally AGA would need the pav/crown #'s; but, I maintain that given stones w/in 1a-2b table/depth %'s that I could make a decision with my eyes. Certain combos are more desirable. When you get into a stone like yours is when the crown & pav. #'s are paramount.
Clearly, one would weed out certain depths & tables. Then, proceed with the viewing from there.
Also, HCA has tightened up a tab. But, when one entered in a table % of 58.9 vs 59% the difference in HCA score was about 1 HCA point. I can not defend that a table difference of 1/10th could make a stone go from an HCA of 1.8 to one of 2.8.
