No, what you wrote falls flat. What it is, is that DxOMark has useful info for those that understand what they are measuring. It is especially difficult for those that lack a certain level of cognitive capacity, for example...

What I wrote stands, DxO makes measuremens for themselves, they choose to publicise these to the world, which is their perogative, some of it is useful to compare cameras and their performance, other stuff, like their ISO measurements are only really useful for their own software.

How does knowing what DxO's RAW converter does with respect to signal amplification affect your choice of Camera and way of photography?

And you can disagree with me all you want, still try to keep a civilized tone here?

Don't get hung up on DxO's definition of ISO. It's merely a reference point relative to a sensor's saturation point. It provides a way to compare the relative noise, color sensitivity and dynamic range between sensors. If you shoot raw then this absolutely applies to what you can expect from the finished image.
