OK think I've got it. Let me put it into my own words:

DR100 does nothing. DR200/400 drops the EV by -1/-2, then uses ISO signal amplification up to 400 to bring the shadows and mid-tones back up to 0EV, but not the highlights which it adjusts to keep under 0EV. This is at a sensor output level (not just JPEG processing) so is available in the RAW files as well.

How did I do? 5/10, 8/10, or 10/10 (surely not)

If broadly speaking I understand this now, then the downside of say DR400 on the smaller X20 sensor, would be higher shadow noise than if I'd used DR100 / ISO100? Maybe not a real life issue, but theoretically am I correct?

PS - please don't bill me in Oz dollars. Our poor unloved pounds don't go very far these days
