I was just reading a few of those FAQs and such including a detailed one on media quality and codes. Reading it popped a question into my head. How exactly is media quality determined? What specifically determines the ranks?
I thought about it and figured that there are two forms of tests: technical/scientific and practical/experience.
Some of the scientific tests are easy; it should be fairly trivial to determine reflectivity for example, but what about chemical decay and distribution, are those considered, and if so how and by whom?
I canâ€™t help but wonder if most of the tests that produce the quality lists are practical ones where some people do test burns of different permutations as well as the compilation of reports of success or failure from lots of people.
Does anyone know what exactly goes into the quality rankings? Is it indeed objective scientific tests, subjective practical tests, or a combination?
