I agree, as Scott123 repeats again and again, thickness factor is key to a great NY pie, which should be light and a bit puffy. For my 16 inch pie, I use a 14 ounce dough ball. The thickness factor is just .07. This has taken some time for me to master. Pythonic, your NY pies look great. Your data is surprising - could you double check for me? 12.5 for a 16 inch pie would be perhaps tf of .06! Wow. I do think some of the best NY places approach this, but it is living dangerously for the home baker! Thanks Mark
