Compared to APS-C models you don't get 2 or 3 stops difference unless you are using DxO's bogus "DR" ratings.

There is a difference, but it's not large.

when, in fact, the difference is as huge as DxOMark claims:

well, yeah, it might help if "they" knew what DR is, how it is measured, and how it applies to photography, so that they would be more able to understand what is "bogus" and what is not and show a little restraint with their self-harming posts.

On the other hand, many other people (in the same thread linked above), seem to have a more competent understanding of what DR is, how large the disparity can be between specific systems, when it matters, and when it doesn't.

And those people, of course, don't "need" an education, but some might find it interesting to understand DR in a little more detail.
