That's got it's own scanning issues (grid like pattern in the darker areas & such as the water), but even it has smoother tones than I've found in scanning my plus-x.This was scanned from Plus-X 35mm, but may very well have been done with a dedicated scanner:
Here are two examples, both have been resampled to 1280 pixels on the long edge (so the antialiasing is covering up as much of the scanner induced noise as possible).

In this one I find there isn't as much detail as in the actual negative.

If you look at the water, sky, or her shirt, you can see less than smooth tones. This one was pushed two stops, but even still, I could make an okay 8x10 from it. There's no way I can print that scan at 8x10 and make it look smooth, 4x6 is as big as it gets.
My intention wasn't to alter the direction of the conversation, and certainly not to go down into some sort of "Plus-X sucks" (because it really realy does not) side track. I just wanted to say don't judge Ultrafine Xtreme based only on looking at scans. The scans change the way the negative looks for the worse, and need to be scaled down to cover up those changes.
