One other point is that it's MUCH easier to compare than to test -- and most magazine pieces (including the ones you quote) are comparisons, not tests. Nor are journalists always outstandingly good experimentalists: I've lost count of the number of times I've seen unstated assumptions, unsupported assertions and changes in mid-test to what is actually being measured.
To a certain extent, as I said in my previous post, even objective testing has an element of comparison in it, especialy with microdensitometers, but most scientists will state their parameters and test conditions. Journalists do not always do this.
I remember these tests, I looked over them for ages when I was first starting out, they did one for b&w films also. Fuji Neopan for me and Perceptol! Unfortunately I recently binned all my old editions when I moved house again. But between 1989 - 1992 I believe.

FeeBay had complete editions of the magazines, so you might be lucky one day.
