While revisiting some of the rambling discussions about mind-cleanness and 41-degree pavilion angles, I ran across this which I thought was interesting. One of the major manufacturers of really nice super-ideal rounds, which often cuts pavilions to 41 degrees, includes this diagram with each stone sold under the brand. It states that the "optimal" pavilion angle is 40.7 degrees (image attached). So regardless of whether the statement is based more on science or on tradition, they're clearly implying that 41 degrees is acceptable but somehow sub-optimal. The fascinating original discussion involved many bona fide experts so I can't add to the knowledge base that wasn't already touched on there except this bit of irony.
