No extra trouble to include the 1004MC, so my work flow almost never changes. But I don't think there is any broadly accepted reason to criticize another for putting all zeros. As stated, I have had requests for that every time I exclude them. Nor do I make any effort to narrowly or specifically define comparability. While I agree with the notion, there are unlikely to be more than one in agreement with each possible definition. If an industry approaching 100 years old has defined it yet, I don't plan to be first.
