Please point out the post where someone said that ONLY spinoramas give sufficient evidence. I missed that one.
What I would offer is that spinorama (CTA-2034) is a format that offers a collection of critical information that makes collective (and interacting) characteristics more obvious.
Let's say you went to the government with a new cartridge, looking for acceptance by the Army ballistics lab. The first thing you would be asked is, "Do you have the drop/drift tables?" If you did not have them, you would most assuredly be shown the door.
You could say that 100 customers had shot the cartridge and every one of them liked it ... there were no complaints. You could say that every shooter hit his target. You could tell the Army lab that there were a lot of things more important than a drop/drift table, such as a temperature/pressure profile. I can tell you from personal experience that the lab personnel would
not be impressed.
This is not because the drift/drop table tells
everything that needs to be known, but because it is the standard of comparison that tells the most critical preliminary information that the Army lab uses to pass judgement ... pass or fail. Same with spinorama.
So I would say that insisting on evidence constitutes neither "dogma" nor "fixed mindsets." It's simply part of doing business.
