I don't claim to know DyR better than anyone else but I have followed the
discussion for some time. So, I'm not sure why what you cite above supports
Austin any better than Julian.

My reading of Julian is that he is in full agreement/compliance with what is
written above. I believe he feels DyR is exactly: 5. The difference between
the maximum acceptable signal level and the
minimum acceptable signal level.
(Modern Dictionary of Electronics, 6th ed.)

My reading of Austin is that he believes DyR is the The difference between
the maximum acceptable signal level and the
minimum acceptable signal level, divided by noise, (where noise is
typically/frequently specified as 10.

Austin, Julian, please correct me where I'm wrong!
