I wasn’t clear in the last post. When I said the pavilion angles are wrong, I mean the comp stone diagram angles are wrong. When you look at the original from facetdiagrams.org the pavilion angles are different but the crown angles are the same in the comp stone. I think someone transposed something when they took the original diagram and formatted it for the competition. The preform on the comp stone guide gives an exact location for the corner girdles but the original is a little fuzzy about sizing the corner. I think the added preform steps throws it off .
