"I have read many, many posts like this, ..., which they all believed performed better than we measured".
What does this tell you?
I have not read onereport other than PZ giving the 18-35 such a bad review.
PZ's own Lens Performance This is most likely spam content has the 18-35 rated higher than: 18-70, 18-135 and 18-200.
Apart from Bjorn, Thom Hogan rates this lens highly. You probably would point out that TH also tested this lens "only" on the D1 and D100.
How that unmentionable person - Ken R?
You can like him or hate him but he has "real world" comparisons between this lens and a bunch of others.
For example, here:

And it was tested on a d3!
KR even goes further to say "this plastic 18-35mm is actually a little bit sharper on my D3 than the 17-35mm f/2.8 AF-S and the 20-35mm AF-D"
Pure fantasy? Perhaps. But he made the statement based on Real images at Real distances. Correct me if I am wrong, but someone mentioned to me that PZ's resolution testing is based on minimum or near-minimum distances. If this is the case, any conclusions are meaningless.
"Sorry, but that doesn't tell us anything about what to expect on a 16 MP DX sensor or even FX."
I made my tests on a D300.
According to PZ, the 18-35mm @35mm and f4.5 (D7000) gives: 2145(center); 1175(border); 1073(extreme)
vs 18-55 VR at f5 2588(center); 2131(border); 1929(extreme)
This is simply wrong. At 35mm the 18-35 is visibly better wide open on my tests against every lens tested against, including the 35mm f/2 at f4!
"we can talk about facts instead of hurt feelings".
Testing and concluding using one and only one sample does not lead to facts.
Hurt feelings? Are you kidding me?
Look, I would like, and I'm sure we would all like PZ to be a reliable site for information on photographic equipment, in particular, lenses!
"please be so kind and loan us your unit"
Granted, you have some problems with getting various samples.
I can not lend you my copy since it is my most used lens. However, I would like to contribute to PZ by lending some others that I do not use so frequently. For example, my trusty 75-150mm Series E, the outstanding 50-135mm f/3.5 and a few others.
And finally, some photos with the 18-35. It's not about resolutions. It's all about the light!
