I don't know of anyone other than Trevor that doesn't recognize the similarity of how Fuji's S#Pro and EXR sensor's can substantially increase the captured DR, by either one or two stop's worth.

The Super CCD technology used by the S Pro series is vastly superior to EXR technology. There really was extended highlight headroom there up to about +3.5 to 4EV.

The same cannot be said for the X10.

If it was the case you would have been able to demonstrate it.  It simply isn't possible, to the best of my knowledge.

When making his own DR measurements does Trevor use step wedges as DPR does in its reviews or a different technique used by any other recognized experts? No, his technique is based on taking pictures of bright white clouds. Ask him about it.

If real world high contrast images cannot show any real improvement of EXR at DR400 over X-Trans at DR200 then I would suggest that their measurements are slightly suspect.

I have yet to see an X10 demonstrate the extra 2EV over an X20, or any other camera for that matter.

Why don't you show us how?

PS  The clouds are used to provide a reproducable, peak white reading which also has easily detectable detail below that level.  It's quite effective, you can easily see when it's clipped or otherwise.

Instead of mocking, why not produce actual results that demonstrate your point?  You've had lots of time to do that...
