I have also an issue, I try to make a pear cut with ratio 1/1.4 with a CZ ,all the diagrams that I found are for ri 1.54. All angle are they to high above critical ? they look ok with gemcad raytrace with little change on the crown ( increase angle ) ..but I m afraid , if anybody have already one for CZ …could be much more easier for me …Main pavillon 41,50 , crown from 33 to 10 degrees …if it help…I attach the design
