how come RN is posting to EDDN as test schema data?
There's a "Use Test Schema" setting for that at the bottom, it defaults to the test schema but you can change the setting. It works that way (in my mind at least) because people who bother to think about and uncheck the box, are the same people most-likely to be taking care to upload good data.
Is the output not considered 'ready for primetime'?
Probably... especially now it doesn't upload system-unknown data, but it depends on a) your definition of primetime, and b) very much, the resolution that the user is running at. It has a colossal effect on OCR quality.
